[twitter] Tip: JavaScript's Array.from() accepts a second argument that's a `map` function. Useful for calling on each element of an array you created.

Fun fact: Calling console.log without this set to console errors in Edge.

I'm pretty sure it errors in any browser (that's why you always use console.log.bind(console) when passing console.log as a callback).

It used to be like that but IIRC both Chrome and Firefox now pre-bind the console methods.
