* Refactoring so CacheWithRedirects has Key and Value type parameters * ModuleResolutionCache or TypeRefDirectiveCache will look in directory before solving, so ResolutionCache doesnt need this check * Test showing module resolution is not shared because resolution cache doesnt update own options * Enable traceResolution on some of the project reference tests * Simplify CacheWithRedirects and ensure the options are set in all common scenarios so cache can be shared between redirects * Make failedlookup etc optional in ResolvedModule/TypeRefefWithFailedLookupLocations Also make accidental public failed lookup internal * Add new API for module and type ref resolution * Store auto type reference resolutions * Modify test to show how using program partially doesnt report resolution diagnostics * Ensure that resolution diagnostics are reported in filePreocessingDiagnostics so they can be reused when program is reused * Some cleanup * Remove the newly added ReoslutionInfo in favor of new APIs * update
TypeScript
TypeScript is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the playground, and stay up to date via our blog and Twitter account.
