Write a function arrayOfLight(x) (get it? Lighthouse…? Come on!) which takes one parameter, a positive number, and returns an array containing all numbers from 0 up to and including the given number.
Example: arrayOfLight(5) should return [0,1,2,3,4,5]
Tips:
An empty array can be created by simply typing []. Adding values to an array can be done by assigning a value to an index directly via the = operator.
