How to use ASCII codes

In JavaScript:

// Get ASCII code from character
const code = "A".charCodeAt(0);  // Returns 65

// Get character from ASCII code
const char = String.fromCharCode(65);  // Returns "A"

In HTML:

<!-- Using decimal value -->
<p>Copyright symbol: &#169;</p>

<!-- Using hex value -->
<p>Copyright symbol: &#xA9;</p>

In CSS:

/* Using content property with ASCII code */
.element::before {
  content: "\00A9";  /* Copyright symbol */
}

About ASCII:

ASCII (American Standard Code for Information Interchange) is a character encoding standard for electronic communication. The standard ASCII character set consists of 128 characters (0-127), while Extended ASCII includes 256 characters (0-255). ASCII codes are widely used in computing, programming, and data exchange.
