How to Append Something to an Array?

Appending something to an array is a common task when working with JavaScript. In this blog post, we will explore different ways to append an element to an array.

Method 1: Using the push() method

The push() method is a built-in JavaScript method that allows us to add one or more elements to the end of an array. Here’s an example:

const myArray = [1, 2, 3];
myArray.push(4);

console.log(myArray); // Output: [1, 2, 3, 4]

Method 2: Using the spread operator

The spread operator is a more modern approach that allows us to concatenate arrays or add elements to an existing array. Here’s an example:

const myArray = [1, 2, 3];
const newArray = [...myArray, 4];

console.log(newArray); // Output: [1, 2, 3, 4]

Method 3: Using the concat() method

The concat() method is another built-in JavaScript method that allows us to merge two or more arrays. Here’s an example:

const myArray = [1, 2, 3];
const newArray = myArray.concat(4);

console.log(newArray); // Output: [1, 2, 3, 4]

These are three different ways to append something to an array in JavaScript. Choose the method that best suits your needs and coding style.
