Does Meta use angular?

Meta (formerly Facebook) primarily uses React—a JavaScript library developed by Meta itself—for building its front-end applications. React is used extensively for building user interfaces across platforms like Facebook, Instagram, and WhatsApp. React has become the go-to front-end framework for Meta, with the company contributing to its development and open-sourcing it in 2013.

Why React, Not Angular?

Meta developed React to meet its specific needs, focusing on performance and scalability. React’s component-based architecture and virtual DOM make it highly efficient for handling dynamic and complex UIs, which is crucial for Meta’s applications that serve billions of users.

Angular at Meta:

While React is the primary front-end framework at Meta, it's possible that Angular could be used in specific, smaller projects or by individual teams for specialized needs. However, Angular is not the main framework of choice for Meta’s large-scale applications.

Key Differences:

• React is a library focused on the view layer, which allows more flexibility with how it integrates with other tools and frameworks.
• Angular, on the other hand, is a full framework that provides a more structured approach to front-end development but is not as widely used at Meta.
