    Now that you're more familiar with string methods, 0:00
    let's put them into practice with a challenge. 0:02
    File names often have their own rules around formatting. 0:05
    It's typical to not allow spaces or special characters in file names. 0:09
    In this challenge, using methods you've learned in this workshop you will create 0:15
    file name strings that follow three rules. 0:20
    Open a workspace or download the project files to complete this challenge. 0:23
    In the project files, 0:28
    we use our same index.html as a front end with a prompt that takes a first and 0:30
    last name and provide the file name using both values. 0:35
    Behind the scenes in our AppJS, 0:41
    you'll complete a function that is called when input is entered by the user. 0:42
    Using string methods remove any spaces from the given name then put 0:47
    an underscore in the place of space between the first and last name. 0:52
    Next, check each letter in the name and make sure it's lowercase. 0:57
    Once you've done this, 1:02
    the function will add a filename extension .jpg to the end of the string and 1:04
    print a message to the screen containing the file name in the correct format. 1:08
    For example, if I type my name, Reggie, capital R space, 1:14
    capital W, Williams and click the OK button. 1:21
    The file name returned is reggie_Williams.jpg, all lowercase. 1:27
    Try breaking this down step by step and 1:34
    using pseudocode to solve this problem before jumping into the text editor. 1:36
    In the next video, I'll show you my solution. 1:41
