And without further ado, your problem-set:

Virginia

Count the number of times you find "Virginia" in a string that is unreasonably long and full of strange characters.

Ascii art lol

We are using JavaScript to display some cool art in our HTML page but something isn't right. See if you can review scramble.js to help you understand what you have to do to the artArray in exercise02.js before writeAscii() uses it to display the messed-up image on the page.

Gettysburg

You are provided a string representation of the Gettysburg Address. Write a function that prints one word of the Gettysburg Address at a time in the console.

Fizz Buzz

FizzBuzz is a common programming puzzle. It requires that you use both loops and conditionals. Variations of this puzzle are widely used as an initial screening question during job interviews. Because this is a classic puzzle, it's easy to look up solutions online. It will be good practice for you to first try to solve the puzzle yourself before searching online.

  • Write a function named fizzBuzz that takes one parameter: maxValue.
  • This function should loop through 1—maxValue (inclusive) and build a string with the following conditions:
    1. If a number is even, concatenate "Fizz, " to the end of the string.
    2. If a number is a multiple of 3, concatenate "Buzz, " to the end of the string.
    3. If a number is both even and a multiple of 3, concatenate "FizzBuzz, " to the end of the string.
    4. If a number is neither even or a multiple of 3, concatenate the number and ", " to the end of the string.
    5. This function should console.log() the final string after maxValue iterations of the loop.

Example

fizzBuzz(12) should display the string 1, Fizz, Buzz, Fizz, 5, FizzBuzz, 7, Fizz, Buzz, Fizz, 11, FizzBuzz,

DOM-ination

In this exercise you are provided some HTML. Follow the instructions in exercise05.js to manipulate the DOM in various ways with JavaScript.

setTimeout

For this exercise you will be working with the setTimeout() function in JavaScript. Your task is to update some text in the HTML file 3 seconds after the page has loaded. See exercise06.js for all the details.

Images In Time

For this exercise you will add a random image to the page every 2.5 seconds using the setTimeout() function in JavaScript. This would be easier with setInterval() but what fun would easy be? Don't worry, we have included some hints in exercise07.js
