How to: June 14, 2025
1. Learn how to build your own full-stack JavaScript apps. freeCodeCamp just published a comprehensive course on the popular MERN Stack. MERN stands for MongoDB, Express.js, React, and Node.js. These are the key tools that a lot of modern web apps use, including freeCodeCamp's platform itself. You'll learn how to build your user interface, handle data routing, and even rate-limit your back end API – so you can stop your app from getting overwhelmed by all those bots out there that are scraping the web for LLM training data.

2. Learn MLOps by building your own system that can run sentiment analysis on YouTube videos. The emerging field of ML Ops is a hybrid of Machine Learning and System Administration (AKA Ops). This comprehensive course will give you a solid project-oriented intro to MLOps. You'll learn about Data Preprocessing, AI Model Benchmarking, Hyperparameter Tuning, Ensemble Techniques and more.

3. On this week's freeCodeCamp podcast, I interview former CTO and prolific programming teacher Hitesh Choudhary. He shares lessons he's learned from personally mentoring dozens of software engineers over the years. He also talks about India's higher education system. And he gives tons of tips for managing your time as a developer. I had a blast learning from Hitesh and I think you will, too.

4. freeCodeCamp published a new handbook on the emerging architecture paradigm of Micro Frontends. You'll learn why this approach is gaining so much steam among software engineers. This handbook will teach you all about Module Federation, Cross-Window Messaging, the Shadow DOM, and more. (full-length handbook): https://www.freecodecamp.org/news/complete-micro-frontends-guide/

5. And we published a handbook on Apple's code signing process. If you want to publish mobile apps in the Apple store, this handbook is a real lifesaver. It would have saved freeCodeCamp's team a ton of time when we were publishing the freeCodeCamp iOS app. We're going to publish a lot more hyper-specific handbooks like this in the future to make developers' lives a bit easier. Bookmark this and you can come back to it when you're ready to publish your first app. (full-length handbook): https://www.freecodecamp.org/news/apple-code-signing-handbook/

Quote of the Week: *"You will not get opportunities unless you prove yourself first. And for proving yourself, there is no hiring manager coming to your door and saying, ‘Hey, please build something for me.’ You have to prove it by contributing to open source."* — Software Engineer and programming teacher Hitesh Choudhary, on this week's freeCodeCamp podcast
