Javascript – Regex to match every occurence of a character except the first one

I’m trying to figure out a regex that will match a = after the last occurrence of a closing bracket.

So in those examples, it should match :

=FUNCTION(LABEL="TEST")=
                       ^ this

=FUNCTION(LABEL="TEST")===
                       ^^^ this

How can I write a regex that follows this requirement?

    Here is one way:

    /(?<=)(?=[^)]*$).*)=/

    If you want the = to be immediately after the bracket with no characters in between:

    /(?<=)(?=[^)]*$))=/

    Use a lookahead:

    =(?=[^)]*$)

    …in which [^)]*$ ensures that there are no closing bracket following it until the end of string.

    Try it on regex101.com.

    Try it:

    console.config({ maximize: true });

console.log('=FUNCTION(LABEL="TEST")='.match(/=(?=[^)]*$)/));
