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];
}
console.log(callerName);
};
function jiminyCricket (){
jamie();
}
jiminyCricket(); // jiminyCricket
I’ve only tested this in Chrome, Firefox, and IE11, so your mileage may vary.
