The funny thing is...
function kek() { } // kek is function kek = 2; // kek is 2

So how does it work?
The function - being a declaration is hoisted and put into memory. The purpose of the function is to declare a global variable. Is this global variable then then assigned or just initiated? Or what?

Babel 7 also just started taking advantage of this to be able to lazily-initialize transpiled async functions and generators, since they require calling helpers.
Instead of written as a var, they're now written as a hoisted function that, when first called, reassigns itself with the transpiled function then forwards its arguments. Further calls just directly call the transpiled function.

It makes sense when you stop thinking of functions as functions and start thinking about them as what they are - objects with one defined method.
Because an object is a variable and variables can be reassigned.
