What syntax is used to create a comment in JavaScript?

In JavaScript, comments are essential for providing clarity and explanations within the code, and the syntax used to create them serves specific purposes. The correct choice indicates that single-line comments are created using two forward slashes (//), which allow developers to comment out a single line of code or create brief notes. This style keeps the comment concise and is particularly useful for quick notes or disabling single lines of code during testing or debugging.

For multi-line comments, the syntax involves using the forward slash and asterisk combination (/* */). This allows developers to encapsulate comments that extend over multiple lines, making it ideal for longer explanations or for commenting out larger blocks of code without affecting the execution of adjacent lines.

Using the correct comment syntax enhances code readability and maintainability, as comments can provide context or documentation without impacting the actual code functionality. This clarity can significantly help team collaboration and future reference for individuals returning to the code later.

Other provided options do not conform to JavaScript commenting standards. For example, single-line comments using "/* comment */" is incorrect, as this syntax is meant for multi-line comments. The use of "#" for comments is a syntax used in scripting languages such as Python, whereas "-- comment --" is associated with SQL. Hence
