Comments (Single-line & Multi-line)

Comments are like sticky notes in your code. They help you and others understand what your code does, but the browser ignores them completely.

Use // for comments that fit on one line:

Use /* */ for comments that span multiple lines:

• Explain what your code does
• Help others understand your code
• Remind yourself what you were thinking
• Temporarily disable code without deleting it

Tip: Good comments explain the “why,” not the “what” – the code already shows what it does!
