Using decodeURIComponent() instead of unescape()

The unescape() function in JavaScript was used to decode a string that has been encoded using the escape() function. However, it’s important to note that unescape() has been deprecated and should not be used in modern JavaScript development. Instead, you should use decodeURIComponent() for most purposes.

Example with unescape() (deprecated):

var encodedString = “Hello%20World%21”;

var decodedString = unescape(encodedString);

console.log(decodedString); // Outputs: Hello World!

Example with decodeURIComponent():

var encodedString = “Hello%20World%21”;

var decodedString = decodeURIComponent(encodedString);

console.log(decodedString); // Outputs: Hello World!

unescape(): Deprecated. Avoid using it.

decodeURIComponent(): The modern and recommended method to decode URI components.
