Function that returns the invocation of its first parameter

Question

On an array of functions, I essentially want to be able to run them all.

Kind of like this, functionArray.map(call) .

Is there any simple way to do this within JavaScript or Lodash other than the obvious (below)

---

functionArray.map(fn => fn())

Not all browsers support this yet

---

functionArray.map(function(fn) { return fn(); })

This is longer than it needs to be

---

function call(fn) { return fn(); })

defining a this function every time you want to use it, this seems like a silly solution, so a problem that might already be defined

Answer 1

I believe the 3rd option is your best bet:

function callSelf(fn) { return fn(); }
functionArray.map(callSelf)
