// Functions













































// Try it out! Here's a simple exercise:
//
// write a function that returns a function that raises a number to a power specified as an
// argument to the previous function. That is, I want to do something like this:
// 
// const cubed = buildFunction(3);
// console.log(cubed(2));          // prints 8
//
// to raise a number to a power, use Math.pow(x, y)
//
// Math.pow(4, 3) -> 64
