The Evolution of Facebook Code: How Much of Mark Zuckerberg’s Original Code Remains?
Have you ever wondered how much of the original code written by Mark Zuckerberg in those first couple of weeks at Facebook still exists today? The answer is simple: very little, if any, remains on the production servers. This article explores the journey of Facebook’s codebase, from its early days to its current state.
The Early Days: Zuckerberg's Original Code
When Mark Zuckerberg first launched Facebook in 2004, the initial prototype was built with PHP. According to Zuckerberg, the original codebase contained only six lines, and it rapidly grew to a more complex system. In the early stages, Facebook was essentially a single-page application with a ton of HTML and PHP code.
Transition to Hack
Facebook recognized the need for a more robust and scalable language to sustain its rapid growth. In 2010, they developed Hack, a statically-typed version of PHP, which allowed them to add type safety and performance optimizations to the codebase. Since then, Facebook has heavily invested in improving and modernizing their codebase, moving away from the original PHP code.
Codebase Evolution
As Facebook continued to grow, the codebase underwent numerous transformations. Many of the core components of the initial codebase have been rewritten and replaced. For instance, Zuckerberg’s early JavaScript libraries have likely been replaced by more sophisticated and feature-rich frameworks. The original databases and backend systems have also been enhanced to handle the massive amounts of data and user interactions.
Repository vs. Production Servers
It is true that there may be remnants of the early library code in the repository, as Github is an invaluable resource for open-source contributions. However, these remnants are likely to be closely guarded intellectual property that would not be publicly accessible. On the production servers, the codebase has been significantly refactored and optimized over the years.
Modernization and Innovation
Facebook has always been at the forefront of technological innovation. They have embraced new programming languages, frameworks, and methodologies to stay competitive. The move to GMscript, a proprietary language, has further solidified the changes in their codebase. For instance, GMscript was introduced to speed up and optimize the rendering process, leading to faster page load times and better user experiences.
Conclusion
In summary, while Mark Zuckerberg’s original code from the early days of Facebook is still a part of the company’s history, very little, if any, remains on the production servers today. The evolution of Facebook’s codebase reflects the company’s commitment to innovation, scalability, and user experience. As Facebook continues to grow, it is likely that the codebase will undergo further transformations, reflecting the latest trends in technology and development practices.
