JavaScript Fundamentals: Logic & Syntax

Code examples (with demo videos!) and extra practice exercises for new learners

I've created a completely new volume of demos and practice exercises for anyone looking to pick up the basics of programming in the context of JavaScript. In a field increasingly dominated by AI code generation, it is essential to have a firm grasp on the fundamentals in order to plan ahead, compose crystal-clear prompts, and recognize errors and poorly-formed code. The only way to build muscle is to exercise it, and learning programming is no different!

1. FORK it to your own GitHub account
2. COPY the link from your new repo on GitHub
3. CLONE it to your local machine. Example:

git clone https://github.com/YourUsername/javascript-fundamentals

If you want to update your forked repository from my parent repository when I add or change things to mine in the future, there are instructions below this section. It will go much easier if you don't ever change the code in main. Instead, do the following:

1. From main, use the command git checkout -b new-branch-name to create your own branch for practicing (example: functions-practice).
2. Practice as much as you'd like in your new branch, making commits as you add code.
3. When you are ready to work on something different in another new branch, use the command git checkout main to return to main and then you can repeat the two steps above.

Set the upstream link:

1. On your local machine, make sure you are in the correct directory in the terminal.
2. Use the command git remote add upstream https://github.com/CodeWithCarrie/javascript-fundamentals

You now have a direct link to my original repo!

Use the command git remote -v to verify that you have linked to both origin (your forked repo) and upstream (my original repo)

Update your repo anytime I make changes in the future:

1. On your local machine, make sure you are in the correct directory in the terminal.
2. If you have any uncommitted changes, stage and commit them.
3. Make sure you are in the branch you wish to update (e.g. main)
4. Use the command git fetch upstream so your local repo has knowledge of changes I made in my repo
5. Use the command git rebase upstream/main to sync your repo

Check to see which branches you already have:

1. You can use the command git branch anytime to see what local branches you have
2. The command git branch -r will show you branches that exist on GitHub (after you've fetched that knowledge)

Each topic will have at least one set of starter code and solution code corresponding to a video on the @CodeWithCarrie YouTube channel, and most topics will include hands-on practice exercises as well. Use the links in the tables below for quick peeks at the code. You can fork your own copy of this repository for practice on your local machine. While individual links are available below for each video, you can also start with the full playlist.

Go forth and learn!

This particular collection of coding exercises focuses solely on JavaScript (occasionally with the readline-sync dependency installed via npm). In my demo videos, I briefly demonstrate Git best practices to impress upon you the importance of making regular commits.
