Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.
Summary
The deprecated unescape() method 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
