5 Best ways to empty an array in JavaScript [How To]

How to empty an array in JavaScript?

var userList =  ['anil','kumar','singh','kushinagar','up','india'];


Method 1: - userList =[];

Method 2: - userList.length=0;

Method 3: - userList.splice(0, userList.length);

Method 4: -
while (userList.length > 0) {

I am not recommended to use "method 4". You can use “method 2” and “method 3” because it is so fast.
