Findindex Function Of An Array In Javascript

In this article, we will discuss the findIndex function of an array in JavaScript.

Purpose

The findIndex function returns the index of the first element of an array that satisfies the particular condition.

Example

Consider the following example.

    <!DOCTYPE html>
    <html lang="en"
        xmlns="http://www.w3.org/1999/xhtml">
        <head>
            <meta charset="utf-8" />
            <title></title>
            <script>
         var arr = [14, 16, 21, 24];
         console.log(arr.findIndex(element => element > 15));
      </script>
        </head>
        <body></body></html>

In the above code, we are finding the index of the first element in the array that is greater than 15. So, the above code will return "1".
