Javascript function to remove leading point

I have a javascript string that has a leading point. I want to remove the leading point using the javascript replace function. I tried the following code.

var a = '.2.98»';
document.write(a.replace('/^(\.+)(.+)/',"$2"));

But that does not work. Any idea?

The following replaces the dot at the beginning of the line with an empty line, leaving the rest of the line untouched:

a.replace(/^\./, "")

Do not perform regular expressions if you do not need it.

Simple charAt()and a substring()or substr()(only if charAt(0)is .) will suffice.
