Change language

Meta updated the list of preferred programming languages for internal development – Hack, C++, Rust and Python

Meta presented a list of programming languages ​​recommended for developing the back end of the company's services. It is noted that the company prefers these languages ​​and does not plan to switch to other technologies in the near future.

The Meta blog reported that in their work, the company's engineers use:

  • C++ and Rust for high-performance projects and high-load backend;
  • Rust for command line tools
  • Python for machine learning, data analysis and for working with Instagram services;
  • Hack for business logic and applications that do not save their state;
  • Java, Go, Haskel and Erlang are allowed for specific projects.

The company said that the presented list has been updated, and Rust has appeared in it. Over the past few years, Rust has become more widely used within Meta projects, and the company believes that it has accumulated enough experience to add the language to the official list of supported technologies.

Meta also said that the company is reluctant to move to new languages ​​and technologies. This is explained by the need for large investments and staff expansion. Also, a large number of supported languages ​​complicates the main stack, and adding new features to services can slow down significantly.
