It seems that filter(Boolean) is quite slow. filter(e => e) is much faster, also faster than lodash. https://www.measurethat.net/Benchmarks/Show/15778/0/compact-vs-filterboolean-vs-filterelement-element

Are we sure? At the end of the day, an identity function used as a predicate will be internally casted to boolean by Array#filter if the type isn't boolean, and in theory doing the conversion ourselves should be either quicker or the same.

also faster than lodash

FWIW, _.compact was the fastest for me by 10M ops/s
