// 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.


function arrayOfLight(x) {
  var array = [];
  for (var i = 0; i < x; i++) {
    array.push(i);
  };
  return array
};

arrayOfLight(5);
