LaTeX is a code-first typesetting system that separates your content from its visual styling. Instead of manually dragging elements around a screen, you write your logic and let the engine render pixel-perfect, consistently formatted PDFs automatically.

We just posted a new course on the freeCodeCamp YouTube channel will take you from absolute beginner to an advanced LaTeX programmer. This course was created by Ammar Taha.

This comprehensive course spans over 41 hours and is broken into six clear, practical phases:

• Phase I: Core Document Setup & Text Formatting – Master basic document architecture, paragraph flows, column layouts, custom margins, and running headers or footers.

• Phase II: Cross-Referencing & Mathematics – Learn to typeset flawless, complex mathematical equations (fractions, matrices, arrays) and automate proofs and theorems.

• Phase III: Code, Algorithms & Figures – Cleanly display source code blocks, format pseudo-code, and manage external images.

• Phase IV: Advanced Tabular Customization – Build beautifully formatted tables complete with cell wrapping, row highlighting, and multi-page layouts.

• Phase V: TikZ Graphics & Vector Drawing – Unlock LaTeX’s built-in vector drawing engine. Learn to program shapes, curves, automated loops, and data plots directly in your document, plus build slide decks using the Beamer class.

• Phase VI: Advanced LaTeX Programming & Bibliographies – Automate dynamic citations, script your build files, and write your own custom packages (.sty) using conditional logic.

Head over to the freeCodeCamp channel and learn how to write documents like a programmer (41-hour watch).

To help you cross that bridge, we just posted a comprehensive deep dive on the freeCodeCamp YouTube channel. Sumit Saha created this course.

This course skips the surface-level tutorials and dives straight into the invisible mechanisms driving the language:

• Scope & Closures: How the engine draws invisible boundaries and allows functions to remember their outer environments.

• Execution Context & Hoisting: Peeling back the curtain to see how code is compiled and processed.

• Prototypes & OOP: Bridging the gap between functional logic and object-oriented programming.

• Event Propagation: Mastering the browser's pulse with event delegation.

• High Performance: Scaling into advanced territories like asynchrony, memoization, and multi-threading.

To give you a preview of the course's conceptual approach, look at how we break down Scope using a simple mental model:

The Golden Rule: A child function can always access its parent's variables, but a parent can never access a child's variables.

var x = 23; // Global Scope (The Parent World)

function myFunk() {
  var y = 10; // Function Scope (The Child World)
  
  console.log(x); // Works! Child can use parent's x (Prints 23)
}

console.log(y); // Crashes! ReferenceError: y is not defined.
                // Parent cannot look inside the child to find y.

The course also dives into Block Scope, illustrating why modern let and const variables are strictly locked inside immediate blocks (like if statements), while legacy var variables leak out to the parent function.

Most AI tools you use day-to-day are basic chatbots: you type a prompt, and they type a reply back. Manus works differently because it is an AI agent. Instead of just answering questions, it runs tasks inside an isolated cloud computer (a sandbox). It can browse the live web, write and execute code, interact with real websites, and handle complex multi-step processes without you having to guide it through every single choice.

The tutorial takes you from setting up a free account to building custom automations and working programmatically. You will learn how to run deep web research, access private sites securely, build sites and prototypes, use the developer API, and more.

Check out the full course on the freeCodeCamp.org YouTube channel to start building your own automations.

We just released a comprehensive course on the freeCodeCamp.org YouTube channel to help you integrate this tool into your professional workflow.

Unlike standard LLM web interfaces, Claude Code acts as an agentic partner. It can search your files, run terminal commands, and execute tests autonomously. It solves the "context gap" by analyzing how your different modules interact without you having to copy-paste dozens of files into a prompt.

This course moves from basic setup to advanced architectural audits. You'll learn things like project scaffolding, architectural audits, autonomous debugging, and multi-file navigation.

You can watch the full course now on the freeCodeCamp YouTube channel (4-hour watch).

This course has been updated for 2026.

This exam mostly deals with cloud computing concepts. Even if you are new to coding, you should be able to prepare for this exam and earn the AWS certification. Andrew Brown created this course. He is a popular instructor and the CEO of ExamPro.

What is the AWS Certified Cloud Practitioner?

The Certified Cloud Practitioner is the entry-level AWS certification that goes through:

• The cloud fundamentals, for example Cloud Concepts, Cloud Architecture, and Cloud Deployment Models

• A close look at the AWS Core Services

• A quick look at the vast amount of AWS services

• Identity, Security, and Governance of the Cloud

• Billing, Pricing, and Support of AWS Services

The course code is CLF-C02 but its commonly referred to as the CCP.

Amazon Web Services is the leading Cloud Service Provider (CSP) in the world and the AWS Certified Cloud Practitioner is the most common starting point for people breaking into the cloud industry.

Consider the AWS Certified Cloud Practitioner if:

• You are new to cloud and need to learn the fundamentals

• You are in the executive, management, or sales level and need to acquire strategic information about cloud for adoption or migration

• You are a Senior Cloud Engineer or Solutions Architect who needs to reset or refresh your AWS knowledge after working for multiple years

No matter your path towards a cloud role, the AWS Certified Cloud Practitioner provides fundamental knowledge that you shouldn't skip.

We just posted a course on the freeCodeCamp.org YouTube channel, taught by Andrew Brown, that explores how to use coding harnesses like Claude Code and Pi Agent to build real-world agentic workflows while benchmarking model performance and hardware requirements.

The course provides a practical look at the current state of open AI by conducting "smoke tests," such as building Flappy Bird clones to evaluate how different models handle real-world coding tasks. You will explore the hardware requirements necessary for local execution, including the VRAM limitations that often make cloud-hosted options more viable for large context windows.

Andrew also evaluates various coding harnesses, like Claude Code and PI Coding Agent. By the end of the course, you will understand which models, such as Kimmy 2.5 and Gemma 4, are most reliable for tool calling and structured code generation.

In our latest course on the freeCodeCamp.org YouTube channel, creator Viswas takes you under the hood of the JavaScript runtime to demystify how asynchronous tasks are managed.

Through clear animations and step-by-step diagrams, this course breaks down the "superpowers" provided by the browser environment. Key topics include:

• The Call Stack: How JavaScript manages the execution order of your program.

• Web APIs: Functionalities like the DOM, setTimeout, and Geolocation that exist outside of core JavaScript.

• The Task Queue vs. Microtask Queue: Discover why promises have a "higher priority" and how they can occasionally lead to the "starvation" of other functions.

• The Event Loop: The bridge that connects everything together, ensuring the stack is empty before pushing new tasks for execution.

Rachel grew up in Westminster, a small California town with a largely Mexican and Vietnamese population. 70% of students at her high school had family incomes so low that qualified for free school lunches. And Rachel was the first student from there to get into Stanford in years.

We talk about:

• The state of computer science education in 2026

• Her thoughts on C++, a language she teaches at Stanford, and its continued importance

• And her tips for how devs should use AI tools without "deskilling" themselves

We just posted a new course on the freeCodeCamp.org YouTube channel, led by instructor and developer Estafania, that will help you leverage the power of automation to help with all your tasks.

Zapier is a no-code platform that allows you to connect and share information between the applications you use every day. The core philosophy is simple: "If this happens, then do that".

• The Trigger: This is the "If this happens" part. It's a specific event in one app (like receiving a new lead in a form).

• The Action: This is the "do that" part. This is the task Zapier performs automatically in another app (like sending a Slack notification or adding a row to a Google Sheet).

This four-hour course takes you from a complete beginner to an advanced user. You will start by setting up a free account and learning the basic building blocks of a "Zap". As you progress, you will dive into modern, AI-enhanced features.

And for people looking to bridge the gap between AI and development, the course concludes with a deep dive into Model Context Protocol (MCP). You will learn how to set up an MCP server to share information from your apps with AI clients like Visual Studio Code and the Gemini CLI. This allows you to interact with your Google Calendar or GitHub repositories directly through an AI interface.
