ES6+ Features

ES6 (ECMAScript 2015) introduced many new features and improvements to JavaScript. These features help make the language more expressive, concise, and powerful. Let's explore some of the key ES6+ (ES2015 and later) features:

1. Template Literals

Template literals, also known as template strings, allow us to embed expressions within a string by using backticks (`). They make string interpolation and multiline strings more convenient. For example:

1// Example 1
2const name = 'John Doe';
3console.log(`Hello, ${name}!`);

2. Arrow Functions

Arrow functions provide a concise syntax for writing function expressions. They use an arrow (=>) and omit the function keyword. Arrow functions also bind this lexically, eliminating the need for the bind, call, or apply methods. For example:

1// Example 2
2const nums = [1, 2, 3, 4, 5];
3const doubled = nums.map((num) => num * 2);
4console.log(doubled);

3. Destructuring Assignment

Destructuring assignment enables us to extract values from arrays or objects into individual variables. It provides a more concise way to assign or access properties. For example:

1// Example 3
2const person = {
3  name: 'John Doe',
4  age: 30,
5  profession: 'Developer',
6};
7const { name, age } = person;
8console.log(`${name} is ${age} years old.`);

These are just a few of the many ES6+ features that enhance JavaScript and make it a more powerful and enjoyable language to work with.

xxxxxxxxxx

// Example 1

const name = 'John Doe';

console.log(`Hello, ${name}!`);

​

// Example 2

const nums = [1, 2, 3, 4, 5];

const doubled = nums.map((num) => num * 2);

console.log(doubled);

​

// Example 3

const person = {

  name: 'John Doe',

  age: 30,

  profession: 'Developer',

};

const { name, age } = person;

console.log(`${name} is ${age} years old.`);
