How to stop function return recursion?

Question

JavaScript

The recursive function must accumulate numbers into an array and be called with additional parentheses (as in the example below) . We want the function to return an array of args . This means that you need to come up with a condition for exiting the recursion. I can't figure out how.

function curry(...args) {
  return (num) => curry(...args, num)
}
curry(2)(8)(5)  // вернёт function, а должно быть [2, 8, 5]
curry(1)(0)(9)(3)(12)  // вернёт function, а должно быть [1, 0, 9, 3, 12]

Answer 1

Currying requires a function with a fixed number of arguments.
A function that uses residual parameters, such as f(...args), cannot be curried this way.
