How does lodash.nthArg work?

lodash.nthArg is a lodash utility function that creates a new function that returns the nth argument passed to it. The n argument specifies the position of the argument to return. If n is negative, the nth argument from the end will be returned. If n is greater than or equal to the number of arguments passed, undefined is returned. This function is useful in situations where you need to get a specific argument from a function, regardless of how many arguments were passed to it.

const { nthArg } = require("lodash");

function foo(a, b, c) {
  const secondArg = nthArg(1)(a, b, c);
  console.log(secondArg);
}

foo(1, 2, 3); // Output: 2

In this example, we import the nthArg function from the lodash library. We define a foo function that takes three arguments, but we only use nthArg to get the second argument and log it to the console. We call the foo function with three arguments 1, 2, and 3, and it logs the second argument, which is 2.
