📝 Walkthrough

Walkthrough

The build script for DTS (declaration file) generation has been modified to reduce the concurrency limit for parallel TypeScript declaration processing from 10 to 5 child processes. A minor formatting adjustment to an else-if condition was also made.

Changes

Cohort / File(s)	Summary
Build Utilities scripts/build/utils/generate-types.ts	Reduced concurrent DTS generation processes from 10 to 5, and added formatting space in else-if condition.

Caution

Some comments are outside the diff and can’t be posted inline due to platform limitations.

⚠️ Outside diff range comments (1)

scripts/build/utils/generate-types.ts (1)

20-24: ⚠️ Potential issue | 🟡 Minor

Stale comment: value mismatch between comment and code.

The comment on lines 22-23 states the limit is 3 ("by trial and error, 3 seems to be the sweet spot"), but the code sets limit(5). Please update the comment to reflect the actual value.

📝 Proposed fix

   // Spawn each entry in it's own separate process, because they are slow & synchronous
   // ...this way we do not bog down the main process/esbuild and can run them in parallel
-  // we limit the number of concurrent processes to 3, because we don't want to overload the host machine
-  // by trial and error, 3 seems to be the sweet spot between perf and consistency
+  // we limit the number of concurrent processes to 5, because we don't want to overload the host machine
+  // by trial and error, 5 seems to be the sweet spot between perf and consistency
   const limited = limit(5);

Verify each finding against the current code and only fix it if needed.

In `@scripts/build/utils/generate-types.ts` around lines 20 - 24, Update the stale
inline comment above the concurrency limiter to match the actual value used:
change the sentence that says "by trial and error, 3 seems to be the sweet spot"
to reference 5 (or otherwise state "5" as the configured concurrency), so the
comment correctly describes the variable assignment where limited is created
with limit(5); ensure the comment around limited/limit(5) is consistent.
