JavaScript to generate random hex codes of color

What is hex code?

A hex code is a six-digit, three-byte hexadecimal number used to represent colors in HTML, CSS, and SVG. The bytes represent the red, green, and blue components of the color. The hex codes are an integral part of HTML for web design and are a key way of representing colors digitally.

Functions to be used for generating hex codes: 

• Math.random() generates any no. between 0 and 1 including decimal. 
• Math.random() * 16 generates no between 0 to 16 including decimal. 
• Math.floor() removes the decimal part. 

Example: In this example, we will generate a random hex color.

javascript

<script>
    // storing all letter and digit combinations
    // for html color code
    var letters = "0123456789ABCDEF";

    // html color code starts with #
    var color = '#';

    // generating 6 times as HTML color code consist
    // of 6 letter or digits
    for (var i = 0; i < 6; i++)
    color += letters[(Math.floor(Math.random() * 16))];

    console.log(color);
</script>

Output:

#E3B0DF 

Note: Output will be different every time the code will get executed.
