JavaScript | unescape() with examples

Prerequisite: JavaScript | escape()

The unescape() function in JavaScript takes a string as a parameter and use to decode that string encoded by the escape() function. The hexadecimal sequence in the string is replaced by the characters they represent when decoded via unescape().

Syntax :

unescape(string)

<script> 
  
// Special character encoded with 
// escape function 
var str = escape("Geeks for Geeks!!!"); 
document.write("Encoded : " + str); 
  
// New Line 
document.write("<br>"); 
  
// unescape() function 
document.write("Decoded : " + unescape(str)) 
  
// New Line 
document.write("<br><br>"); 
  
// The exception 
// @ and . not encoded. 
str = escape("To contribute articles contact us" +  
                "at [email protected]") 
document.write("Encoded : " + str); 
  
// New Line 
document.write("<br>"); 
  
// unescape() function 
document.write("Decoded : " + unescape(str)) 
  
</script> 

Output :

Encoded : Geeks%20for%20Geeks%21%21%21
Decoded : Geeks for Geeks!!!

Encoded : To%20contribute%20articles%20contact%20us%20at%[email protected]
Decoded : To contribute articles contact us at [email protected]
