Comments are an essential tool in any programming language, allowing developers to annotate their code with helpful descriptions, reminders, or explanations. In , comments are used to provide context or to temporarily disable specific lines or blocks of code without deleting them.
In , single-line comments are created using the ##
symbol. Any text following this symbol on the same line will be ignored by the compiler.
Here's an example:
In this example, the text "This line will not be read by the compiler" is a comment and will not affect the execution of the code.
For longer comments that span multiple lines, provides a multi-line comment syntax. You can start a multi-line comment with ###
and close it with another ###
.
Here's how you can create a multi-line comment:
In this example, the three lines between the ###
symbols are all part of a multi-line comment and will be ignored by the compiler.
Code Documentation: Use comments to document your code, explaining the purpose of specific functions, algorithms, or logic.
Debugging: Temporarily disable certain lines or blocks of code during debugging without deleting them.
Collaboration: Leave notes or reminders for other developers working on the same project.
Use comments judiciously. While they are helpful, excessive or unnecessary comments can clutter your code.
Always ensure that your comments are clear, concise, and relevant to the code they're annotating.
Remember that comments are for developers, not the compiler. They won't affect the execution or output of your program.
