[JavaScript] function question

[mindauggas]

write an if statement that checks if the parameter exponent is 0. If it is, return 1 (a base case).

var power = function(exponent, base){
	if (exponent === 0){
		return 1;
	}
};

power();

It does not work, ca anyone tell why?

You are not calling your function correctly.
1. The power function has two parameters. You are calling it with no parameters.
2. The power function returns a value, so you need to store or otherwise use the return value.

var retValue = power(0, 10);

After the code above runs, retValue should be set to 1.

Also, you don't need to use === in your comparison, since you're just comparing numbers, not objects. The == operator should work just fine.
