        compiles the TypeScript code to JavaScript #
    - - you can capture errors
        
        before your script runs
      - uses static checking
        
        to detect errors in the code
        
        without running it

  - - - function add(num1: number, num2: number) { return num1 + num2; } console.log(add('2', '3'));
    - - will flag the error
      - but still produce valid JavaScript output
- - - - but helps during development
  - - - but built into TypeScript
