is it possible to throw your local variable out to globally so that you can reuse it?

e.g.

 
let x = 'a random string'

function test() {
  let y = 'bzzz'
  return y
}

 
let x = 'a random string'

function test() {
  let y = 'bzzz'
  return y
}

I want to use the 'y' variable globally, is that possible?

running let y = test(); in the global scope would be the best way generally it's a bad idea to implicitly change values in the global scope from inside a function, because a couple of weeks from now you might forget that you're doing that and that can cause bugs that are hellish to fix

I see, thanks for pointing that out

needing to do that is generally a good sign you need to refactor somethiing

I was thinking of this, and i think i would just use a clean object to store global variables (not really global, but it's organized )

const globals = { } //or what ever you want to name it

function test() {
  globals.y = "foo";
}
test();
console.log(globals.y);

const globals = { } //or what ever you want to name it

function test() {
  globals.y = "foo";
}
test();
console.log(globals.y);

Its a bit more chars, but its way more organized. And you don't have to worry about reserved names on window

yeah I think storing it inside an object makes it look cleaner, thanks!
