Initializes an array containing the numbers in the specified range where `start` and `end` are inclusive with their common difference `step`.
- Use `Array.from()` to create an array of the desired length, `(end - start + 1)/step`, and a map function to fill it with the desired values in the given range.
- You can omit `start` to use a default value of `0`.
- You can omit `step` to use a default value of `1`.
- Use `Array.from()` to create an array of the desired length.
- Use `(end - start + 1)/step` and a map function to fill the array with the desired values in the given range.
- Omit the second argument, `start`, to use a default value of `0`.
- Omit the last argument, `step`, to use a default value of `1`.
