Look through these now and then use them to test yourself after doing the assignment:
- Which data type is NOT primitive?
- What is the difference between single, double, and backtick quotes for strings?
- Which type of quote lets you embed variables/expressions into a string?
- How do you embed variables/expressions into a string?
- How do you escape characters in a string?
- What is the difference between slice/substring/substr?
- What are methods?
- What are the three logical operators and what do they stand for?
- What are the comparison operators?
- What is nesting?
- What are truthy and falsy values?
- What is the syntax for an if/else if/else conditional?
- What is the syntax for a switch statement?
- What is the syntax for a ternary operator?
- What is the relationship between null and undefined?
- What are conditionals?
Depending on what kind of work you’re doing, you might end up working more with pieces of text rather than numbers. A string is simply a piece of text… and is a fundamental building block of the language.
- Read and code along with yet another MDN tutorial on the topic.
- Go through this lesson to learn a more about what you can do with strings… be sure to do the exercises at the end!
- Vocabulary time: a method is a bit of functionality that is built into the language or into specific data types. In the previous lesson you learned a few methods that can be used on strings such as
search. An exhaustive list of methods that can be used on strings can be found here.
Now it’s time for the fun stuff… So far we haven’t done much with our programming that you couldn’t do with simple math skills. Sure, we’ve told our computer how to do the math, so that makes it quicker, but the essence of programming is teaching the computer how to make decisions in order to do more involved things. Conditionals are how we do that.
- Step one in learning about conditionals is making sure you have a good grasp on comparisons and logical operators.
- This article reinforces the concept and provides several interesting examples of how you could use it building websites.
- This article covers the same basic concept (read through it as a review!) And more importantly offers the usual ‘tasks’ at the bottom of the page!
- This tutorial teaches you about the
switch statement, which comes in handy when you have multiple conditions.
To give you a good bit of practice, we have created an online classroom on repl.it. In general we believe that it’s best to work on programming on your own computer rather than in an online environment but we’ll get to that soon enough.
- The classroom and lessons can be found here. Do the lessons in order. You do not have to sign up or login to repl.it to do the course, but doing so makes the user experience a little nicer.. you can submit your answers to check them and see ‘model solutions’ on a couple of the lessons.
