Question

I am trying to achieve the following for both @ or #.

function split(val) {
    return val.split(/@/);
}

function extractLast(term) {
    return split(term).pop();
}

Any help really appreciated!

Answer 1

Try

val.split(/@|#/g);

The | is the regex alternation operator ie ‘OR’. The g flag makes the expression match globally (ie all instances)

See this fiddle

As Pointy notes the g flag isn’t necessary here. It is however necessary if wanting to find all matches within a string in JS regular expressions.
