Cultivating a Culture of Interest and Engagement: Moving Beyond the ‘Work for Salary’ Mentality

Posted on by nullplex

In today’s fast-paced world, it’s becoming increasingly common to see employees, especially from the younger generation, switching jobs every 1-2 years. The primary reason behind this trend? A higher salary. While financial growth is important, the obsession with chasing the next pay check often overshadows other critical aspects of work life, such as personal interest, company alignment, and professional growth. This “work for salary” mentality not only impacts individual productivity but can also lead to long-term negative consequences.

The “Work for Salary” Trap:

Many employees fall into the trap of working solely for a pay check. They often overlook their own interests, passions, and whether their work style aligns with the company’s expectations. When the primary motivation is money, employees may find themselves disengaged from their tasks, leading to lower productivity and a lack of fulfilment. This focus on salary can prevent individuals from fully committing to their roles, ultimately hindering both personal and professional growth.

The hidden Costs of Job-Hopping:

Switching jobs frequently may seem like a quick way to secure salary hikes, but it comes with hidden costs. Constantly moving from one company to another can create a reputation of instability. Employers may view such candidates as unreliable or lacking commitment, making it harder for them to secure long-term, meaningful positions in the future. Moreover, job-hopping prevents employees from fully developing their skills and expertise in any one role, limiting their potential for career advancement.

The Importance of Professionalism and Ethics:

Professionalism and ethics play a crucial role in any workplace. When employees focus solely on salary, they may compromise on these values, leading to unethical behaviour such as cutting corners or failing to meet deadlines. This not only damages the individual’s reputation but can also harm the company’s culture and success. Maintaining a strong sense of professionalism and adhering to ethical standards is essential for building trust, respect, and long-term success.

Beyond Salary: What Really Matters:

While salary is undoubtedly an important factor in any job, it’s not the only one that matters. Other factors such as the value and respect one receives from colleagues, opportunities for growth, and the work environment play a significant role in overall job satisfaction. A supportive and positive work environment can lead to higher levels of engagement, creativity, and productivity. When employees feel valued and respected, they are more likely to stay committed to their roles, resulting in long-term success for both the individual and the company.

The Future Impact of a Salary-Driven Mindset:

Employees who prioritize salary over all else may face challenges in the future. As the job market becomes increasingly competitive, employers will seek candidates who are not only skilled but also committed and passionate about their work. A history of frequent job changes may raise red flags for potential employers, limiting future opportunities. Additionally, the lack of deep engagement in any one role can prevent employees from reaching their full potential, leading to stagnant career growth.

Cultivating a Culture of Interest and Engagement:

To move beyond the “work for salary” mentality, it’s essential for both employees and employers to cultivate a culture of interest and engagement. Employees should take the time to explore their passions, align their work with their personal values, and seek out roles that offer more than just a paycheck. Employers, on the other hand, should focus on creating an environment where employees feel valued, respected, and motivated to contribute their best work.

Conclusion:

By prioritizing factors such as job satisfaction, professional growth, and ethical behaviour, both employees and companies can achieve greater success. Moving beyond the “work for salary” mindset allows individuals to find true fulfilment in their careers, leading to higher productivity, stronger relationships, and long-term professional growth.

Understanding Promises in JavaScript: A Comprehensive Guide

Posted on by nullplex

Promises give us the option to perform asynchronous computation easily and more simply.

before Promises callbacks were used which leads to callback Hell,

to overcome this Problem Promises were introduced. 

Example of promises

const timer = time => new Promise((resolve,reject)=> setTimeout(resolve(“promise is resolved.”),time));

timer(3000)

.then((val)=> console.log(“Timer executeds — “+val))

.catch((err)=> console.log(” promise is rejected — “+err))

.finally(()=>console.log(“Promise is closed”))

Promise consists of 3 state of execution –

  1. Before the result is ready, the Promise is pending.
  2. If a result is available, the Promise is fulfilled.
  3. If an error happens, the Promise is rejected.

Note: A Promise is settled if inside function logic is executed. (if it is either fulfilled or rejected). only once the promise is settled.

Inside the promise, there are two operations to change the state. After you have invoked either one of them once.

  1. resolve – promise has been executed properly.
  2. reject – promise has been rejected.

How to consume the promises –

    .then() block handle the resolved output by promises.

    .error() block catch the error if the rejected state is sent by promise.

    .finally() block execute every time of resolve or reject of promise.

    Note – promise chaining is the concept where we can handle the resolved output by promises. in multiple. then blocks.

            .then()

            .then()

            .then()

What if we have multiple promises –

    There are methods provided by promises to handle all at once.

  • Promise.all() –  it is static method takes an iterable of promises as input and returns a single Promise when all promises are fulfilled.

const promise1 = Promise.resolve(1);

const promise2 = Promise.resolve(2);

const promise3 = Promise.resolve(3);

Promise.all([promise1,promise2,promise3]).then((values)=>{

    console.log(“all promises values – “,values);

})

  • Promise.allSettled() – it is static method takes an iterable of promises as input and returns a single Promise when all promises are settled. ( either it may resolve or reject. )

const promise4 = Promise.resolve(4);

const promise5 = Promise.resolve(5);

const promise6 = Promise.reject(6);

Promise.allSettled([promise4,promise5,promise6]).then((values)=>{

    console.log(“all promises values – “,values);

})

  • Promise.any() = static method takes an iterable of promises as input and returns a single Promise.

    This returned promise is fulfilled when any of the input’s promises are fulfilled, with this first fulfillment value.

   note – if any one of the rejected promises comes then also it will give output.

const promise7 = Promise.reject(0);

const promise8 = new Promise((resolve) => setTimeout(resolve, 100, ‘quick’));

const promise9 = new Promise((resolve) => setTimeout(resolve, 500, ‘slow’));

Promise.any([promise7,promise8,promise9]).then((values)=>{

    console.log(“all promises values – “,values);

})

  • Promise.race() = static method takes an iterable of promises as input and returns a single Promise.

    This returned promise settles with the eventual state of the first promise that settles

    note – if any one of the rejected promises comes then also it will give error.

// const promise11 = Promise.reject(0);

const promise11 = new Promise((resolve) => setTimeout(resolve, 100, ‘quick’));

const promise12 = new Promise((resolve) => setTimeout(resolve, 500, ‘slow’));

Promise.race([promise11,promise12]).then((values)=>{

    console.log(“all promises values – “,values);

})

basically both below used to This function flattens nested layers of promises.

Promise.resolve() – return promise resolve with value.

Promise.reject() – return the promise rejected.

Advantages of promises:

  1. Easy to Read Code and maintain.
  2. Advantage over callbacks.
  3. can handle multiple asynchronous tasks.

Disadvantages of promises:

  1. Complex Error Handling.
  2. For beginners it will create confusion.
  3. Hard Debugging error.

At the end – Promises is a Great Tool to handle Async Tasks. By using Async await we can handle Promises a lot easy way.

Single Page Application vs Multiple Page Application

Posted on by nullplex

A Single Page Application (SPA) and a Multiple Page Application (MPA) are two common web development architectures, each with distinct characteristics, use cases, and approaches to user interaction.

Single Page Application (SPA)

A Single Page Application is a web application that loads a single HTML page and dynamically updates the content as the user interacts with the app. Instead of reloading the entire page for every user interaction or navigation, SPAs load necessary components and data using AJAX or fetch requests, enabling smoother and faster experiences.

Characteristics:
– Dynamic Content: SPAs load content dynamically as users interact, typically using JavaScript (e.g., React, Angular, Vue.js).
– Single Load: The application is loaded once, and only data is fetched or sent to the server when needed, avoiding full-page reloads.
– Routing with JavaScript: Routing (navigating between different parts of the app) is handled on the client side, usually with libraries like React Router.
– API-centric: SPAs frequently communicate with backend APIs (e.g., RESTful or GraphQL) to fetch data or perform operations asynchronously.
– Responsive and Fast: User interactions feel fast and responsive because only specific components update, and no page refresh is needed.

Advantages:
– Fast and Responsive UX: Only parts of the page are updated, reducing the need for full-page reloads.
– Smooth Transitions: Navigating between views is seamless, creating a fluid experience.
– Offline Support: SPAs can cache necessary resources and data, allowing the app to function offline with technologies like Service Workers.
– Reusability of Components: UI components can often be reused across the application, which speeds up development.

Disadvantages:
– SEO Challenges: SPAs traditionally struggle with SEO because search engines might not fully crawl or render JavaScript-heavy content.
– Initial Load Time: The first load may take longer since more resources (e.g., JavaScript files) are needed to load the app.
– JavaScript Dependency: Since most logic happens client-side, the application heavily depends on JavaScript being enabled and functioning correctly.

Examples of SPAs:
– Gmail
– Facebook
– Twitter
– Google Maps

Multiple Page Application (MPA)

A Multiple Page Application is a traditional web application that loads a new HTML page from the server whenever a user interacts or navigates. Every time a user clicks on a link or submits a form, the server sends a new page back to the browser.

Characteristics:
– Full-page Reloads: Each user action results in a new page request from the server, leading to full-page reloads.
– Server-side Rendering (SSR): Each page is rendered on the server and sent to the client. This makes MPAs SEO-friendly as the content is always visible to search engines.
– State Management: Since the state (i.e., the state of the UI, user data, etc.) is often reset with each page load, maintaining a consistent state across pages is more complex without relying on additional tools.
– Separate Pages: Each page is a separate HTML document, and the application uses server-side logic to manage and serve different pages.

Advantages:
– Better SEO: Since content is rendered server-side, search engines can easily index the content of each page.
– Simpler to Develop: Traditional page-based architecture is easier for developers familiar with server-side rendering and doesn’t require complex client-side JavaScript.
– Security: Since most rendering happens server-side, there is generally less exposure to client-side vulnerabilities.

Disadvantages:
– Slower Navigation: Full-page reloads result in slower navigation and less fluid user experience.
– Resource Intensive: More server requests are made for each navigation action, and larger amounts of data (complete pages) are transferred.
– Complex UI State Management: Managing the UI state across multiple pages requires more effort, especially when passing data between pages or keeping parts of the interface consistent.

Examples of MPAs:
– Traditional eCommerce websites (e.g., Amazon)
– News websites (e.g., BBC, The New York Times)
– Content-heavy blogs

Key Differences Between SPA and MPA

FeatureSPAMPA
Page Reloads No (content is loaded dynamically)Yes (full-page reloads for each request)
Performance Fast navigation after initial loadSlower navigation due to reloads
SEOChallenging, though solutions exist (e.g., pre-rendering)Better SEO as content is server-rendered
Development ComplexityHigher (requires managing client-side logic)Lower (server-side logic is more straightforward)
User ExperienceSmooth, app-like experienceMore traditional web experience
Initial LoadLonger due to loading JS filesTypically shorter, but may load extra unused assets
Offline SupportPossible with caching mechanismsRarely supported, difficult to implement
State ManagementEasier with client-side frameworksHarder to maintain across different pages

When to Use SPA vs. MPA

– Use Single Page Applications if:
  – You need a highly interactive app (e.g., social media platforms, dashboards, SaaS products).
  – You want a fast, responsive experience for users once the app is loaded.
  – SEO is not the primary concern or you have workarounds for SEO (e.g., server-side rendering).

– Use Multiple Page Applications if:
  – SEO is crucial (e.g., blogs, eCommerce sites, news portals).
  – You have a content-heavy site with less interactivity.
  – You prefer server-side rendering and simpler development.

Each approach has its own strengths and trade-offs, and the decision to use SPA or MPA depends on the specific requirements and goals of the project.
