What's Ramda equivalent to underscore.js 'compact'?

Question

Does Ramda have a function to remove false values from a list?

I know we can simply do var compact = R.filter(R.identity); but am I missing the ready-made function?

Answer 1

There's no direct equivalent, but R.filter(R.identity) and R.filter(Boolean) both work.

R.reject(R.isNil) is useful for filtering out null/undefined.

Answer 2

You can use Ramda Adjunct's compact which works like the Underscore / Lodash equivalents.

RA.compact([0, 1, false, 2, '', 3]); //=> [1, 2, 3]
