Here we consider how to empty an array in javascript. Lets start with one example here. Suppose we have an array in javascript as shown below.

var array = ["1", "2", "3"];

For clearing this array, you can use following method.

var array = ["1", "2", "3"];
array = [ ];

This will set the variable array to a new empty array. Another method will be set the length of array to Zero.

var array = ["1", "2", "3"];
array.length = 0;
