The deprecated unescape()
function computes a new string in which hexadecimal escape sequences are replaced with the character that it represents. The escape sequences might be introduced by a function like escape
. Because unescape
is deprecated, use decodeURI
or decodeURIComponent
instead.
Note: Do not use
unescape
to decode URIs, use decodeURI
instead.Syntax

Parameters
str
- A string to be decoded.

A new string in which certain characters have been unescaped.

function is a property of the global object.
