array combine js code example

Example 1: merge array in js

//for ES5
var array1 = ["Rahul", "Sachin"];
var array2 = ["Sehwag", "Kohli"];

var output = array1.concat(array2);
console.log(output);

//for ES6, we use spread operators to concat arrays

var array1 = ["Dravid", "Tendulkar"];
var array2 = ["Virendra", "Virat"];

var output = [...array1, ...array2];
console.log(output);

Example 2: js combine arrays

const array1 = ["Vijendra","Singh"];
const array2 = ["Singh", "Shakya"];
const array3 = [...array1, ...array2];

Example 3: javascript merge array

// ES5 version use Array.concat:
let array1 = ["a", "b"]
let array2 = ["1", "2"]
let combinedArray = array1.concat(array2);
// combinedArray == ["a", "b", "1", "2"]

// ES6 version use destructuring:
let array1 = ["a", "b"]
let array2 = ["1", "2"]
let combinedArray = [...array1, ...array2]
// combinedArray == ["a", "b", "1", "2"]

Example 4: combine 2 arrays javascript

//ES6 using the spread operator
const itemsA = [ 'Lightsaber', 'Mockingjay pin', 'Box of chocolates' ];
const itemsB = [ 'Ghost trap', 'The One Ring', 'DeLorean' ]
const allItems = [ ...itemsA, ...itemsB ];
