Javascript Program To Remove Duplicate Array Elements Tecadmin

This tutorial described to you to remove duplicate array elements using JavaScript.

Example

Output: In the above example, the value “Green” was defined twice in the array. As a result, you see only one instance of Green. You may be thinking about element 100.
