Code examples (with demo videos!) and extra practice exercises for 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!
This collection of coding exercises focuses on JavaScript, Node and NPM modules, and Jest. While my JavaScript Fundamentals demos included Git commits, this collection and future collections will typically not cover that under the assumption that learners have developed the habit already.
Important
You need to deepen your problem-solving skills and core understanding of syntax and code composition independently before you can integrate AI tools in your workflow and become a more efficient developer. My learning resources are designed to do just that!
If you are unfamiliar with the basics of JavaScript, I recommend starting with my JavaScript Fundamentals Series before continuing below.
Most topics include the following:
- Demo video on YouTube at this full playlist on the @CodeWithCarrie channel
- Starter and solution code for the demo
- Starter and solution code for the corresponding hands-on practice
See the tables below for specific links for each topic.
Tip
Please read my detailed instructions for how to fork, clone, and sync this repository.
Make sure you have npm and Node.js installed before continuing with any of the exercises below on your local machine.
