Self-Driving Car with JavaScript Course – Neural Networks and Machine Learning

By freeCodeCamp.org
Published: May 12, 2022

“
freeCodeCamp.org Learn how to create a neural network using JavaScript with no libraries. In this course you will learn to make a self-driving car simulation by implementing every component step-by-step. You will learn how to implement the car driving mechanics, how to define the environment, how to simulate some sensors, how to detect collisions, and how to make the car control itself using a neural network.

The course covers how artificial neural networks work, by comparing them with the real neural networks in our brains. You will learn how to implement a neural network and how to visualize it so we can see it in action.

Twitter (Elon Musk) announced that they will no longer allow free promotion of certain social media platforms on Twitter. The platforms that are restricted are Facebook, Instagram, Mastodon, Truth Social, Tribel, Nostr, Post, and 3rd-party social media link aggregators such as linktr.ee, lnk.bio.

Let’s take a look at this new policy and figure out how we can continue to provide value to our audiences.

Improve your online presence with a FREE link-in-bio generator that provides a unique URL and is not affiliated with any 3rd-party link aggregation services. You get full ownership of the generated page, preventing bans from social media platforms like Twitter

Even though console log may not always be the best way to debug JavaScript, we all use it. So, install the Turbo Console Log extension in VS Code to turbo charge your logs. Select any variable that you want to log, press CTRL+Alt+L (for log) and it will automatically add the log for you.

Not only does it add a log, but it adds to it the file, variable name, and the variable value to make them easy to find in the console. You can customize what’s included in each log in the settings. But that’s not even the best feature of this extension. You can press ALT+Shift+C to comment all log messages in a file.

ALT+Shift+U to uncomment all logs in a file.

And when you’re done debugging, press ALT+Shift+D to delete all logs in the file so no one will ever know you were using console logs to debug!
