• typescript is compiled javascript. it generates definition files with the following suffix: *.d.ts
    • these files can show up when you use "Go to Definition" - know that what you're looking at is not the source code in these cases but the definition of the source code
    • to find the actual source code, look for files under src/ directory
  • src vs lib
    • when your navigating the codebase, your IDE will show you the same file in both lib and src folder
      • lib folder has the compiled assets and is rarely what you want
