javascript - Filtering an Array based on another Boolean array -

say have 2 arrays:

const data = [1, 2, 3, 4] const predicatearray = [true, false, false, true]

i want return value be:

[1, 4]

so far, have come with:

pipe(   zipwith((fst, scnd) => scnd ? fst : null)),   reject(isnil)  )(data, predicatearray)

is there cleaner / inbuilt method of doing this?

solution in ramda preferred.

if want ramda solution reason, variant of answer richsilv simple enough:

r.addindex(r.filter)((item, idx) => predicatearray[idx], data)

ramda not include index parameter list function callbacks, reasons, addindex inserts them.
