使用 Ramda 将函数列表应用于 arguments 列表

Question

Is there a function in Ramda to apply a list of functions to a list of arguments similar to juxt() but where each function only gets supplied with the argument at the corresponding index in the list of arguments? Something similar to:

pipe(zip, map(([a, b]) => a(b)))([func1, func2], ['arg1', 'arg2']);

Is there a better way to do this?

Answer 1

Use R.zipWith which creates a new list out of the two supplied by applying the function to each equally-positioned pair in the lists.

You can also replace the callback with R.call, which invokes the first argument, and passes the rest as it's parameters.

 const { zipWith, call } = R; const fn = zipWith(call); const func1 = R.add(1); const func2 = R.add(2); const result = fn([func1, func2], [1, 2]); console.log(result);
