unescape() function computes a new string in which hexadecimal escape sequences are replaced with the characters that they represent. The escape sequences might be introduced by a function like

A new string in which certain characters have been unescaped.
unescape() is a function property of the global object.
unescape() function replaces any escape sequence with the character that it represents. Specifically, it replaces any escape sequence of the form
X represents one hexadecimal digit) with the character that has the hexadecimal value
XXXX. If the escape sequence is not a valid escape sequence (for example, if
% is followed by one or no hex digit), it is left as-is.
Note: This function was used mostly for URL encoding and is partly based on the escape format in RFC 1738. The
unescape() function does not evaluate escape sequences in string literals. You can replace
%uXXXX to get a string that can be handled by
unescape("abc123"); // "abc123" unescape("%E4%F6%FC"); // "äöü" unescape("%u0107"); // "ć"
