Comments and Delimiters in JavaScript


  Comments in JavaScript are a useful way to document code and make it easier to understand for other programmers (or for yourself in the future!). Additionally, delimiters like the semicolon are important for structuring code correctly.


Comments:


  • Single-line comments: Use // to indicate that the rest of the line is a comment.

  • Multi-line comments: Use /* */ to include comments across multiple lines.

Delimiters:

  • Semicolon (;): Although optional in many cases, it's recommended to use it to avoid ambiguities.

Purpose:

  • Document and explain code for other developers or for yourself.
  • Test and debug code by temporarily disabling parts of it.
  • Use delimiters for correct program execution.
