The computer-science README focuses on outlining the curriculum, while freeCodeCamp's README provides more information about the project itself, including licensing and contribution guidelines.
:books: Freely available programming books
Pros of free-programming-books
- Extensive collection of free programming resources across various languages and topics
- Community-driven project with frequent updates and contributions
- Easy to navigate and find specific resources based on programming languages or subjects
Cons of free-programming-books
- Lacks interactive learning elements or hands-on coding exercises
- No structured curriculum or learning path for beginners
- Limited to curated links and resources, without original content creation
Code comparison
While a direct code comparison isn't relevant for these repositories, we can look at how they structure their content:
free-programming-books:
## Index
* [Languages](#languages)
* [Platform Agnostic](#platform-agnostic)
* [Web Development](#web-development)
freeCodeCamp:
const availableLangs = [
'arabic',
'chinese',
'english',
'spanish',
// ... more languages
];
freeCodeCamp focuses on providing a structured learning platform with interactive coding challenges, while free-programming-books serves as a comprehensive directory of free programming resources. freeCodeCamp offers a more guided learning experience, whereas free-programming-books provides a vast collection of materials for self-directed learning across various programming topics.
Interactive roadmaps, guides and other educational content to help developers grow in their careers.
Pros of developer-roadmap
- Provides visual roadmaps for various tech career paths
- Regularly updated with current industry trends and technologies
- Offers a clear, structured learning path for beginners
Cons of developer-roadmap
- Less hands-on coding practice compared to freeCodeCamp
- Focuses more on breadth than depth of knowledge
- Limited community interaction and support
Code Comparison
While a direct code comparison isn't relevant due to the nature of these projects, we can compare how they present information:
developer-roadmap (README.md):
## 👨💻 Frontend Roadmap
[![](https://img.shields.io/badge/-Download%20PDF%20-0a0a0a.svg?style=flat&colorA=0a0a0a)](https://roadmap.sh/roadmaps/frontend.pdf)
![Frontend Roadmap](./img/frontend.png)
freeCodeCamp (curriculum structure):
const CERTIFICATION_FIELDS = {
responsive: 'Responsive Web Design',
javascript: 'JavaScript Algorithms and Data Structures',
frontend: 'Front End Development Libraries',
// ...
};
developer-roadmap focuses on visual representation of learning paths, while freeCodeCamp structures its curriculum programmatically for interactive learning.
Master programming by recreating your favorite technologies from scratch.
Pros of build-your-own-x
- Focuses on hands-on, project-based learning
- Covers a wide range of technologies and concepts
- Encourages deep understanding by building from scratch
Cons of build-your-own-x
- Less structured curriculum compared to freeCodeCamp
- Fewer community resources and support
- May be more challenging for absolute beginners
Code Comparison
While a direct code comparison isn't relevant due to the nature of these repositories, we can compare their approach to learning:
freeCodeCamp example (JavaScript):
function confirmEnding(str, target) {
return str.slice(str.length - target.length) === target;
}
build-your-own-x approach (conceptual):
# Build your own programming language
def tokenize(source_code):
# Implement tokenization
def parse(tokens):
# Implement parsing
def interpret(ast):
# Implement interpretation
The freeCodeCamp example shows a specific coding challenge, while build-your-own-x encourages building entire systems from scratch.

Pros of coding-interview-university
- Focused specifically on interview preparation and computer science fundamentals
- Provides a structured, self-paced learning path
- Includes links to free resources and explanations for each topic
Cons of coding-interview-university
- Less interactive compared to freeCodeCamp's hands-on coding challenges
- Narrower scope, primarily targeting software engineering interviews
- May require more self-discipline to follow through without built-in progress tracking
Code Comparison
While both repositories focus on learning programming concepts, they don't typically include code snippets directly in their main README files. However, freeCodeCamp does provide coding challenges in its curriculum. Here's an example of a simple JavaScript challenge from freeCodeCamp:
function convertToF(celsius) {
let fahrenheit = celsius * (9/5) + 32;
return fahrenheit;
}
convertToF(30);
coding-interview-university doesn't include code snippets in its main content, as it's more of a curated list of resources and topics to study.
Both repositories serve different purposes:
- freeCodeCamp offers a comprehensive, interactive coding curriculum
- coding-interview-university provides a focused roadmap for interview preparation and computer science fundamentals
The choice between them depends on your learning goals and preferred study method.

Pros of system-design-primer
- Focused specifically on system design and scalability concepts
- Includes visual diagrams and illustrations to explain complex topics
- Provides a curated list of external resources for further learning
Cons of system-design-primer
- Less hands-on coding practice compared to freeCodeCamp
- Narrower scope, focusing primarily on system design rather than a broad range of programming topics
- May be more challenging for absolute beginners in software development
Code Comparison
While both repositories are primarily educational resources, they have different approaches to code examples. freeCodeCamp provides more hands-on coding exercises, while system-design-primer focuses on high-level concepts and pseudocode.
freeCodeCamp example (JavaScript):
function confirmEnding(str, target) {
return str.slice(str.length - target.length) === target;
}
system-design-primer example (Python pseudocode):
def consistent_hashing(self, key):
return bisect.bisect_left(self.ring, key) % len(self.nodes)
Both repositories serve valuable purposes in the developer community. freeCodeCamp offers a comprehensive curriculum for learning various programming languages and web development, while system-design-primer provides in-depth knowledge on designing scalable systems. The choice between them depends on the learner's specific goals and current skill level in software development.

Certifications
freeCodeCamp.org offers several free developer certifications. Each of these certifications involves building 5 required web app projects, along with hundreds of optional coding challenges to help you prepare for those projects. We estimate that each certification will take a beginner programmer around 300 hours to earn.
Each of these 50 projects in the freeCodeCamp.org curriculum has its own agile user stories and automated tests. These help you build up your project incrementally and ensure you've fulfilled all the user stories before you submit it.
You can pull in these test suites through freeCodeCamp's CDN. This means you can build these projects on websites like CodePen and Replit - or even on your local computer's development environment.
Once you've earned a certification, you will always have it. You will always be able to link to it from your LinkedIn or resume. And when your prospective employers or freelance clients click that link, they'll see a verified certification specific to you.
The one exception to this is if we discover violations of our Academic Honesty Policy. When we catch people unambiguously plagiarizing (submitting other people's code or projects as their own without citation), we do what all rigorous institutions of learning should do - we revoke their certifications and ban those people.
