What does a single line comment in js represent?

In JavaScript, a single-line comment is represented by double forward slashes (//). It will ignore the content after the slash to the end of the line and is used to explain the code or provide other information.

What is used to represent a single-line comment in JS

In JavaScript, a single-line comment uses double forward slashes (/ /)express.

The specific syntax is as follows:

<code>// 这是单行注释</code>

When the JavaScript interpreter encounters a double forward slash, it ignores everything after the slash until the end of the line. For example:

<code>console.log("Hello, world!"); // 输出信息

// 这是另一条单行注释</code>

In this example, the second line is ignored by the interpreter and will not be executed.

Note:

• Multi-line comments use different syntax in JavaScript, i.e. starting with /* and ending with */end.
• Both single-line comments and multi-line comments are used to add comments to code to explain the purpose of the code or provide additional information.
