State of
APIs

Developers’ workflows change rapidly.
Here are the insights you helped us collect on the state of APIs in 2021.

What are our favorite languages?

We asked questions to determine what languages developers use and which ones they prefer. JavaScript rebounded this year to increase its lead, and TypeScript snuck into the top 5 most commonly used languages. Older languages’ usage continued to fall — see Java, PHP, C#, and .NET moving down and to the left.
