Control flow
Lesson 1 of 1
  1. 1
    Now that we’ve got the parts of JavaScript, let’s see what they can do. In this unit, we’ll explore how we can take those parts, and create decision trees, games, and much more. In programming, ma…
  2. 2
    If you think about what we’ve been doing so far, we’ve been writing instructions for computers. That’s all programming really is: a list of instructions for computers. The main difficulty of bein…
  3. 3
    if/else statements are made even more powerful with comparison operators. There are two comparisons you might be familiar with: - Less than: You may also recognize these: - Less than or eq…

    Before we move on, let’s circle back to else if statements. Using else if is a great tool for when we have a few different conditions we’d like to consider. else if is limited however. If we want…
  8. 8
    Way to go! We just learned a lot of control flow concepts: - if/else statements make binary decisions and execute separate code based on a condition. - We can add extra conditions with to if/else …
