how to spread an array in javascript code example

Example 1: array spread operator in javascript

let arr1 = ['A', 'B', 'C'];

let arr2 = ['X', 'Y', 'Z'];

let result = [...arr1, ...arr2];

console.log(result); // ['A', 'B', 'C', 'X', 'Y', 'Z']
// spread elements of the array instead of taking the array as a whole

Example 2: javascript spread operator

function myFunction(v, w, x, y, z) { }
let args = [0, 1];
myFunction(-1, ...args, 2, ...[3]);
