for Loop Range Generator

In addition to while loops, JavaScript also has for loops. In most common cases, for loops and while loops can be used interchangeably (though sometimes one is more convenient than the other). For example, I rewrote our range generator using a for loop. Run it and convince yourself that it produces the same result.

Elements of a for Loop

The condition in a for loop has three parts, each separated by a semicolon:

1. Initialize a loop variable (here: nextVal)
2. Define an ending condition (here: nextVal <= endVal)
3. Update the loop variable (here: nextVal = nextVal + 1)

When we wrote the while loop, we had to initialize a loop variable before the while loop and update it inside the while loop. The for loop just moves those two steps into the for loop's condition.

Tests

In a previous challenge, you updated makeRange to allow for a stepSize. For example, makeRange(1, 10, 2) would return [1, 3, 5, 7, 9].

To pass the tests, update the function signature and the for loop to allow for different step sizes.
