ScriptdrillPipe functions together
A JavaScript exercise from Scriptdrill. Solve it with a code editor in your browser that runs your function against example and hidden tests, and it is checked the moment you submit.
The task
Return a function that passes its input through `fns` from left to right: `pipe(f, g, h)(x)` is `h(g(f(x)))`. The first function may take several arguments; the others get one. With no functions, the result returns its first argument unchanged.
What this exercise teaches
Only the first function sees the original arguments, so it is called separately with ...args; reduce then threads one value through the remaining functions. Handling the empty list first makes pipe() an identity function.
A hint if you get stuck
Return `(...args) => ...`. Call the first function with all of `args`, then `reduce` over the rest, feeding each result into the next.
