Advanced JavaScript Coding Practices for Modern Web Apps

JavaScript is a vital programming language for building modern web applications. However, coding in JS is not as easy as it may seem. You need deep knowledge, understanding of web app development, and advanced coding practices to create more interactive and user-responsive web apps. This article will guide you through the essential advanced JavaScript coding practices to help you become a better web app developer.

1. Modular JavaScript Code

Writing modular and reusable code not only saves time but also boosts readability and maintenance. In modular coding, you break your application into smaller and reusable chunks. When coding in JS, you use IIFEs (Immediately Invoked Function Expressions), and modules to maintain and manage your code better.

// Example of IIFE(function(){    // your code here})();// Example of module using revealing module patternconst module = (() => {   let x = “reusable”;   const reveal = () => {      console.log(x);   }   return {      reveal   }})();

2. Use Arrow Functions

Arrow functions are a new feature introduced in ES6, and they provide a more concise way of writing functions. Arrow functions can reduce a codebase’s size and increase readability and maintainability. When coding in JavaScript, you should use arrow functions wherever possible to reduce the code and improve its clarity.

// Example function using arrow functionconst multiplyTwoNumbers = (a, b) => a * b;

3. Async/await Instead of Promises

Promises are beneficial in representing asynchronous operations. However, they can be difficult to read and understand. ES7 introduced async and await, which is a more … Read More
