GraphQL

FB developed it to deliver efficient and precise data to its billions of users.

It's not just an architecture style; it's also a query language.

It allows clients to ask for specific data as they need. This means no more over-fetching or under-fetching of data.

This leads to more efficient network communication and faster responses.

Its flexibility and efficiency make it a strong choice for applications with complex data requirements.

It has a steep learning curve and may be overkill for simpler applications as it needs more processing on the server side due to its flexible querying capabilities.
