Facebook:Programming Languages used by Facebook

Introduction:

Few platforms in the digital age have had as much of an impact on society as Facebook. Facebook has billions of users globally, but its success isn't random; rather, it comes from careful software design. This essay explores the complex technological layers that underpin the biggest social media network in the world.https://preettheman.medium.com/these-are-the-programming-languages-facebook-uses-90cece3127d9

                                                                       

PHP's Basis:

PHP is a server-side scripting language that was used as the foundation for Facebook's backend. The first framework for managing dynamic material and user interactions was provided by PHP. But as the platform grew, it became clear that PHP had limitations, which inspired the creation of original fixes.

Changing Performance with Hip Hop:

 Facebook released Hip Hop for PHP (HPHP), a proprietary compiler that translated PHP code into C++, in order to solve PHP's performance issues. Performance was greatly improved by this compilation process, leading Facebook to manage massive traffic volumes without sacrificing responsiveness.

Facebook mostly uses JavaScript

 on the front end to generate exciting and engaging user experiences. Frontend development at Facebook was transformed with the creation of React.js, a JavaScript toolkit for creating user interface components. The component-based architecture of React made code organization easier and increased reusability, which improved user experience.

Data Management:

MySQL was Facebook's main database management system in its early years. But as the platform developed to handle petabytes of data and billions of users, conventional relational databases were found to be insufficient. Facebook made the switch to the distributed NoSQL database Apache Cassandra in order to satisfy its needs for fault tolerance and huge scalability.

Using the Power of HHVM:

 Facebook created the Hip Hop Virtual Machine (HHVM) to improve PHP execution even more. Hack, Facebook's statically typed version of PHP, and PHP were both run at high speeds under HHVM. HHVM provided near-native PHP code execution speeds, which improved the platform's scalability and efficiency.

Graph QL:

The Facebook-developed Graph QL turned out to be a revolutionary approach to API development. Graph QL minimizes over- and under-fetching of data by enabling clients to specify exactly the data they require, in contrast to typical RESTful APIs. Facebook's use of Graph QL improved developer productivity and efficiency by streamlining data fetching across its many services.

Real-Time Communication via Messenger Protocol:

 A key feature of the network, Facebook Messenger, depends on its own messaging protocol. Facebook's Messenger Protocol, which is based on the lightweight messaging protocol MQTT, allows users to communicate in real time and ensures consistent messaging experiences across devices.

In conclusion:

 Facebook's rise to prominence in the social media space cannot be exclusively ascribed to its inventive functionalities or extensive utilisation. The success of the platform is largely due to a well-designed software architecture that works behind the scenes. Every technology, from Apache Cassandra and Graph QL to PHP and JavaScript, is essential to creating Facebook's unmatched user experience. With an infrastructure built for performance, innovation, and scalability, Facebook continues to lead the way in the growth of digital communication.
