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
