JavaScript/TypeScript Balance

The proportion of developers who write the entirety of their code in TypeScript keeps increasing, and may soon represent a majority of respondents.

How do you divide your time between writing JavaScript and TypeScript code?

Compiled Code Balance

A natural consequence of writing typed code (at least today) is depending on a build step, which is the case for the vast majority of us.

Build Step Advantages

If we did want to envision a build-less future, the first step would no doubt be native type support in JavaScript.

AI Code Generation

While respondents do not yet produce a majority of their code with AI, the balance is quickly shifting, with code being the result of AI output increasing from 20% to 29% year-over-year.
