JavaScript chop/slice/trim off last character in string
You can use slice! You just have to make sure you know how to use it. Positive #s are relative to the beginning, negative numbers are relative to the end.
js>"12345.00".slice(0,-1)12345.0
You can use the substring method of JavaScript string objects:
s = s.substring(0, s.length - 4)It unconditionally removes the last four characters from string s.
However, if you want to conditionally remove the last four characters, only if they are exactly _bar:
var re = /_bar$/;s.replace(re, "");
