Q90 / 100

What does the "--isolatedModules" compiler flag warn against?

Correct! Well done.

Incorrect.

The correct answer is B) Code constructs that cannot be correctly compiled when each file is transpiled independently, such as re-exporting types without "export type"

B

Correct Answer

Code constructs that cannot be correctly compiled when each file is transpiled independently, such as re-exporting types without "export type"

Explanation

isolatedModules ensures every file can be safely transpiled in isolation (as tools like Babel or esbuild do), flagging things like non-type re-exports of types that require whole-program type information.
