COMMON COMMANDS

  tsc
  Compiles the current project (tsconfig.json in the working directory.)

  tsc app.ts util.ts
  Ignoring tsconfig.json, compiles the specified files with default compiler options.

  tsc -b
  Build a composite project in the working directory.

  tsc --init
  Creates a tsconfig.json with the recommended settings in the working directory.

  tsc -p ./path/to/tsconfig.json
  Compiles the TypeScript project located at the specified path.

  tsc --help --all
  An expanded version of this information, showing all possible compiler options

  tsc --noEmit
  tsc --target esnext
  Compiles the current project, with additional settings.
