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.
Text
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.
Text
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.
Text
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.
Text
const fruits1 = ['apple', 'banana'];
const fruits2 = ['orange', 'grapes'];
const allFruits = [...fruits1, ...fruits2];
console.log(allFruits); // output: ['apple', 'banana', 'orange', 'grapes']These are some of the ways to add elements to an array in JavaScript. Choose the method that best fits your requirements.
