    For the last challenge, we need to use the forEach method to capitalize all 0:00
    the strings in the months array and store them in the array named capitalizedMonths. 0:04
    To start, I'll copy and paste the code into Atom to make it easier to read. 0:10
    I started my solution to this challenge like all of the others, 0:19
    by stubbing out the call to the for each method. 0:22
    So months.forEach. 0:25
    I used month, the current value parameter name, 0:29
    followed by a fat arrow and a set of curly braces. 0:33
    To get the capitalized month, I called the string to uppercase method, 0:37
    to convert the month text into uppercase letters. 0:41
    So, first our variable const, 0:45
    capitalizedMonth=month.toUppercase. 0:47
    Then I pushed the capitalize month onto the capitalizedMonths array, 0:58
    capitalizedMonths.push(capitalizedMonth). 1:03
    And that's the solution. 1:08
    And just like we did before, we could also eliminate this code block. 1:10
    To do that, we would cut this code and 1:17
    place it inside of the call to the push method. 1:20
    That allows us to eliminate this intermediate variable and 1:24
    the curly braces. 1:28
    And that's it! 1:31
    Nice job sticking with it and completing all of the code challenges in this course. 1:33
    Thanks for practicing array iteration methods with me. 1:38
