WeakMap vs Map

[syarul]

I want to ask. Is there are reasons to fallback to Map when WeakMap is not available? https://github.com/michael-klein/hookuspocus/blob/d77f0b4dac894d1c945c02f9b837320ee8ac39bb/src/core.js#L1 https://github.com/michael-klein/hookuspocus/blob/d77f0b4dac894d1c945c02f9b837320ee8ac39bb/src/core.js#L7 The way I see it Map won't accept objects as keys. There's an alternative to WeakMap if it's not available by using polyfill weakmap-polyfill by @polygonplanet
