In this post we will discuss the different ways to empty an array in JavaScript. Let’s declare an array for explanation purposes.

let arr = [1,2,3,4,5];

Setting length to 0

arr.length = 0;
console.log(arr);
//[]

Assigning to empty array

arr = [];
console.log(arr);
//[]

Remove all the array elements

while (arr.length > 0) {
	arr.pop();
}

console.log(arr);
//[]

Splice the array

arr.splice(0, arr.length);

console.log(arr);
//[]
