Getting Started with ES6+: An Introduction to Modern JavaScript


3 min read

Hello fellas, Welcome to the Ultimate Guide to ES6+ to get yourself familiar with modern JavaScript Features and start implementing them in your code, to make it more readable, concise and optimized.

ARE YOU EXCITED ๐Ÿ”ฅ? Let's get right into it.

What the heck is even ES6?

ES6, also known as ECMAScript 2015, is a significant update to JavaScript that was released in 2015. It includes several new features, such as let and const declarations, arrow functions, template literals, classes and much more we are gonna discuss later, that make JavaScript code more concise, expressive, and maintainable.

Let's Dive into Modern ES6 Features

1. Template Literals:

Template Literals is a great way to concatenate the variables with strings, Numbers or other primitive data types.

  • use backticks `` instead of " " and then wrap the variable inside ${ variable }.

2. Destructuring Objects:

By destructuring objects, we can avoid writing that large chunk of code again & again.

without Destructuting we would have to Access values from objects like this :

  • you might be familiar with the "DRY" concept, don't repeat yourself we are clearly violating that law Above so we gotta do something right?, that's where Destructing Objects comes into place.

  • This way we can simply access the name instead of having to type ""

Look how easy it became to access those same values.

3. Destructuring Arrays:

It's a fairly simple one :

By destructuring the Array we can save some of our steps like below:

4. Arrow Functions:

Arrow functions are an awesome addition to JavaScript! They bring a concise syntax to function writing, allowing for lexical scoping of the 'this' keyword. With arrow functions, you can define functions in a more compact and streamlined manner.

6. Object Literals:

ES6 introduced exciting enhancements to object literals! They now come packed with new features, including concise method syntax, computed property names, and shorthand property and method definitions. These additions provide greater flexibility when it comes to object initialization and manipulation, making your code more dynamic and expressive.

7. Modules:

ES6 introduced native support for modules, enabling developers to organize and encapsulate their code into separate files, making code refuse and maintenance easier.

Module A

Module B

8. Promises:

promises provide a better way to handle asynchronous operations in JavaScript, simplifying the complexity of dealing with callbacks and enabling a more structured and readable code flow.

9. Classes:

ES6 introduced a class syntax for creating objects with a more familiar object-oriented programming approach. Classes offer a cleaner and more intuitive way to create reusable object blueprints.

And there you have it, fellas! The magnificent world of ES6+ is at your fingertips. By embracing these modern JavaScript features, you can unlock a whole new level of coding prowess. So go forth, implement these enhancements in your projects, and witness the magic unfold. Get ready to write cleaner, more concise, and optimized code like never before. Remember, the power of ES6+ is yours to wield. Happy coding, my friends! ๐Ÿ”ฅ๐Ÿš€
