Think Like a Computer Science Professor

By freeCodeCamp.org
Published: Jul 20, 2022

“
See how to think like a computer science professor. You will observe Radu’s thought process as he codes a project for the first time. Many tutorials demonstrate how to build something that the instructor has already fully planned out beforehand. But in this video, you learn what really goes into building a project from scratch. And he does it all without even referencing the Internet.

Radu Mariescu-Istodor has a PhD in computer science. He teaches computer science at a university as well as on his YouTube channel.

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

By freeCodeCamp.org
Published: May 12, 2022

“
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.
