PyTorch, React, GraphQL, Jest, FBOSS for data center networking, the list goes on.

Companies dream of creating just one of these.

Not to mention tons of contributions to VR. They may have mismanaged the PR on that, but the product, as it exists is quite a thrill.

Didn't they also contribute heavily to PHP?

[xhkkffbf]

Yes, their virtual machine was amazing. It brought all of the JIT technology and really sped up their PHP stack.

Now which of those are used by facebooks users

[baobabKoodaa]

Well, let's start with React. It's used by 100% of Facebook users.

[seydor]

React is an innovation, in what exactly? It bloats the web with needless javascript and abstractions. It's a convenient shortcut for people making native mobile apps. It's not taking the world forward

Almost every request is graphql. ML also… all the ads and feeds use it.

rocksdb, zstd compression, buck build system are also noteworthy that have far reaching impact across the industry.

PyTorch was based on Torch, which facebook did not create.
