You can write a multiple-line comment in JavaScript using the following syntax:
/* This is a multi-line comment.
It can span multiple lines.
You can write anything you want here. */Here's a breakdown of the syntax:
- *`/`**: This starts the multi-line comment.
- *`/`**: This ends the multi-line comment.
- Anything between
/*and*/: This is considered a comment and will be ignored by the JavaScript interpreter.
Example:
// This is a single-line comment.
/* This is a multi-line comment.
It can span multiple lines.
You can write anything you want here. */
console.log("Hello, world!");In this example, the console.log("Hello, world!"); line will be executed because it is not part of the multi-line comment.
Key Points:
- Multi-line comments can be used to explain code, disable code temporarily, or add notes for future reference.
- You can use nested multi-line comments, but it's generally not recommended for readability.
- Unlike single-line comments, multi-line comments can be used to comment out multiple lines of code.
Practical Insights:
- Use multi-line comments to document your code and make it easier to understand.
- Use them to temporarily disable code blocks for testing or debugging purposes.
