bookDart Comments

Developers use comments to make code easier to understand. The Dart interpreter ignores them, allowing you to explain what the code does or clarify its purpose.

void main() {
  print('Correct'); // Outputs word Correct to the console
}

You can comment out code blocks to prevent them from running. This is helpful for avoiding runtime errors or testing specific parts of your code.

void main() {
  // print("This is a test!");
  print('Hello, World!');
  // print Hello, World!"'()
}

Dart supports single-line comments // and multi-line comments /* */.
