Implement a range function that returns an iterable object which can be used in a for...of loop. The range function should accept two arguments, from and to, and produce a sequence of numbers from from to to, inclusive.
for (let num of range(1, 4)) {
console.log(num);
}
// Output:
// 1
// 2
// 3
// 4
