what is Composition? It is actually not that difficult to understand, see @dan_abramov 's explanation.
Here you are asked to create a
pipe() function, which chains multiple functions together to create a new function.
Suppose we have some simple functions like this
const times = (y) => (x) => x * y const plus = (y) => (x) => x + y const subtract = (y) => (x) => x - y const divide = (y) => (x) => x / y
pipe() would be used to generate new functions
pipe([ times(2), times(3) ]) // x * 2 * 3 pipe([ times(2), plus(3), times(4) ]) // (x * 2 + 3) * 4 pipe([ times(2), subtract(3), divide(4) ]) // (x * 2 - 3) / 4
- to make things simple, functions passed to
pipe()will all accept 1 argument
Let's try to solve this problem within 5 mintues.
