dystroy's answer is correct, but in the interest of completeness: you could use a negative look-ahead assertion, too:

var s = 'f}oo}bar';
s = s.replace(/}(?!.*})/, '');
console.log(s);//f}oobar

Basically this regex replaces a single closing curly brace, if it's the last (or only) } char in the string.
how it works:

  • }: matches a literal } char
  • (?! negative look-ahead: matches the } only if it is not followed by:
  • .*}: zero or more chars, followed by a closing curly

You can do this to remove the last } of a string :

s = s.replace(/\}([^}]*)$/,'$1')
