Question

Const R = require('ramda'); const addition = R.curry((a,b) => a +

b)

const square = (x) => x * x

const multi = (a) => {

R.pipe(
addition(a),
square
)
}

arr = [1,2,3]

const result = arr.map(x => multi(1))

console.log(result)
//[undefined,undefined,undefined]

why i am getting undefined ?

Source: const pow = R.flip(Math.pow); const square = pow(2); const multi = R.pipe(R.add, square); const arr = [1,2,3]; const result = R.map(R.partialRight(multi, [ 1 ]), arr) result Result: [ 4, 9, 16 ]
