Proposal: Symbol.breakLoop for exit from forEach loops

[xlaywan]

Now there is no way to exit from forEach loops.

iterable.forEach(item => {
  if (item == 'what we need')
    return Symbol.breakLoop // loop breaks here
})

Traditional equivalent

for (let item of iterable) {
  if (item == 'what we need')
    break
}

Or just Symbol.break.

What's wrong with using .some / .every and using return true / return false to break out?

Also ES6's Array#find will return the item you're looking for, or undefined, stopping the iteration as soon as the predicate returns true.
