Every Function In Javascript

In this article, we will discuss every function in JavaScript.

Purpose

The "every" function checks each and every element of an array against a certain condition. If every element satisfies the condition then the function returns true.

If any one of the elements does not satisfy the condition then the function returns false. Please note that if any of the elements returns false then the function will not check the remaining elements.

Example

    <!DOCTYPE html>
    <html lang="en"
        xmlns="http://www.w3.org/1999/xhtml">
        <head>
            <meta charset="utf-8" />
            <title></title>
            <script>
         var arr = [18, 16, 21, 24];
         console.log("Array 1: " + arr.every(element => element > 15));
         
         arr = [18, 14, 21, 24];
         console.log("Array 2: " + arr.every(element => element > 15));
      </script>
        </head>
        <body></body></html>
