How to use the spread Operator In Javascript

The spread operator (…) can determine the length of an array by spreading its elements into a new array and then accessing the length property of the new array. This concise approach simplifies counting array elements in JavaScript.

Example:

JavaScript
const array = [1, 2, 3, 4, 5];
const newArray = [...array];
const length = newArray.length;
console.log(length); 

Output
5
