TypeScript · Middle · Question 70 of 75

What do the `types`/`typesVersions` and the `exports` `"types"` condition in `package.json` do?

✓Correct answer: Tell TypeScript where to find the declaration files for a package (or for each entry point)
2Install @types packages
3Enable strict mode for consumers

Explanation

With exports, put the types condition first in each entry, otherwise TypeScript may resolve the JS file and find no types.
