I am attempting to modify function arguments within another function and then pass them back to the calling function. My approach is as follows:
function func(a,b,c) {
console.log(arguments, a, b, c); //[1, true, "a"] 1 true "a"
arguments[0] = 2;
console.log(arguments, a, b, c); //[2, true, "a"] 2 true "a"
arguments = ArgumentsToNumber.apply(this, arguments);
console.log(arguments, a, b, c); //[2, 1, NaN] 2 true "a"
}
function ArgumentsToNumber() {
for (let i = 0; i < arguments.length; i++) {
arguments[i] = Number(arguments[i]);
}
return arguments;
}
func(1, true, 'a');
The goal is to make changes in variables a, b, and c.
