JavaScript Array Add Method

JavaScript provides various methods to add elements to an array. In this blog, we will discuss some of these methods in detail.

Push Method

The push() method adds one or more elements to the end of an array and returns the updated length of the array.

const fruits = ['apple', 'banana'];
fruits.push('orange');
console.log(fruits); // output: ['apple', 'banana', 'orange']

Unshift Method

The unshift() method adds one or more elements to the beginning of an array and returns the updated length of the array.

const fruits = ['apple', 'banana'];
fruits.unshift('orange');
console.log(fruits); // output: ['orange', 'apple', 'banana']

Concat Method

The concat() method merges two or more arrays and returns a new array that contains all the elements.

const fruits1 = ['apple', 'banana'];
const fruits2 = ['orange', 'grapes'];
const allFruits = fruits1.concat(fruits2);
console.log(allFruits); // output: ['apple', 'banana', 'orange', 'grapes']

Spread Operator

The spread operator (...) can be used to add elements from one array to another.

const fruits1 = ['apple', 'banana'];
const fruits2 = ['orange', 'grapes'];
const allFruits = [...fruits1, ...fruits2];
console.log(allFruits); // output: ['apple', 'banana', 'orange', 'grapes']
