How do you find out the caller function in JavaScript when use strict is enabled?

For what it’s worth, I agree with the comments above. For whatever problem you’re trying to solve, there are usually better solutions.

However, just for illustrative purposes, here’s one (very ugly) solution:

'use strict'

function jamie (){
    var callerName;
    try { throw new Error(); }
    catch (e) { 
        var re = /(\w+)@|at (\w+) \(/g, st = e.stack, m;
        re.exec(st), m = re.exec(st);
        callerName = m[1] || m[2];

function jiminyCricket (){

jiminyCricket(); // jiminyCricket

I’ve only tested this in Chrome, Firefox, and IE11, so your mileage may vary.
