How to check if an Array is Not Empty in JavaScript - Step by Step Examples

How to check if an Array is Not Empty in JavaScript ?

To check if an array is not empty in JavaScript, you can use the length property of the array.

In this example,

Finally, we log whether the array is not empty or not.

let numbers = [1, 2, 3];
let notEmpty = numbers.length !== 0;
console.log(`Array is not empty: ${notEmpty}`);
