Empty an Array in JavaScript

// 1) Assigning it to a new empty array
// This is the fastest way to empty an array:
a = [];


// This code assigned the array a to a new empty array. It works perfectly if you do not have any references to the original array.
// See the following example:
let b = a;
a = [];
console.log(b); // [1,2,3]

// Code language: JavaScript (javascript)
// In this example, first, the b variable references the array a. Then, the a is assigned to an empty array. The original array still remains unchanged.

// 2) Setting its length to zero
// The second way to empty an array is to set its length to zero:
a.length = 0;

// The length property is read/write property of an Array object. When the length property is set to zero, all elements of the array are automatically deleted.

// 3) Using splice() method
// The third way to empty an array is to remove all of its elements using the splice() method as shown in the following example:
a.splice(0,a.length);

// Code language: CSS (css)
// In this solution, the splice() method removed all the elements of the a array and returned the removed elements as an array.

// 4) Using pop() method
// The fourth way to empty an array is to remove each element of the array one by one using the while loop and pop() method:

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