Maybe it's a little bit longer, but you don't have to create an array just to use the prototypes concat method.
Instead of
[].concat([1,2],[3,4])
you could also write that one:
Array.prototype.concat([1,2],[3,4])
nice, thanks for sharing that 👍
Just for fun I tried it on jsperf and the first one is way faster. Never thought that. But it's probably just a micro optimization.
