TypeScript 5.3 provides a new programmatically accessible option on the compiler host object to control the amount of JSDoc parsing that the TypeScript parser will perform. The `tsc` command line tool now uses the `ParseForTypeErrors` value which only parses JSDoc comments that may affect type checking and is considered a good default for tools such as the Angular CLI. The Angular CLI will now attempt to use the `ParseForTypeErrors` value as well when available. Projects will need to use TypeScript 5.3+ for this option to be available. No behavior changes will occur on TypeScript 5.2 projects. This should not only provide a small improvement to build times but also a reduction in overall memory usage.
