to empty an array in JavaScript?

let var arrayList = ['a', 'b', 'c', 'd', 'e', 'f'];

Method 1:-

arrayList = [];        

This is the most easiest way to make an empty array.

Just assign a blank array .

Method 2:-

arrayList.length = 0;        

If you make array length to zero using inbuild length function of JavaScript then you can get empty array .

If you want in details please visit my previous article .

Method 3:-

arrayList.splice(0, arrayList.length);        

You can use also splice method to blank an array . so the first element of this method is the position to remove items index and the last one is how many number of items to be removed.

Here the start index is zero and number of items are array length, it means all elements of an array .
