    Another way you might write a loop is with the for of loop, like for each, 0:00
    for of creates a loop that repeats an action a given number of times. 0:04
    You create a for of loop with the keyword, for 0:09
    followed by a parentheses and curly braces. 0:14
    Inside the parentheses, you provide for 0:18
    of a variable that represents the current item being processed in the loop. 0:21
    This is very similar to the movie parameter we just used inside for each. 0:25
    So I'll again call the variable movie with var movie, and 0:30
    you could also the let and const keywords I mentioned earlier here in place of var. 0:35
    Now I'll follow the variable with the keyword of and 0:40
    the name of the array we're looping over, in this case, movies. 0:44
    Inside the curly braces you provide a statement or 0:49
    action to be carried out for each element that gets passed into the loop. 0:52
    I'll simply log each movie title to the console 0:57
    with console.log and pass it in movie. 1:00
    So as you can see, this loop statement is pretty simple to read. 1:05
    It almost reads in plain English, for 1:09
    every movie of the movies array, log it to the console. 1:13
    I'll give this a save, refresh the browser, and 1:19
    now over in the console we see a list of all the titles stored in the movies array. 1:23
