How to use line breaks in js

The following characters can be used as line breaks in JavaScript: \n (line feed), \r (carriage return), \r\n (carriage return and line feed, usually used on Windows systems). Primarily used to separate strings into multiple lines, it is useful when creating multi-line blocks of text, separating code snippets, and creating line breaks in the output. Different operating systems and environments may use different line breaks, and you should always check the target platform's convention.

Line breaks in JavaScript

How to use line breaks?

In JavaScript, you can use the following characters as line breaks:

• \n: LF (line feed)
• \r: CR (carriage return character)
• \r\n: CRLF (carriage return and line feed character, usually used in Windows systems)

When to use line breaks?

The main purpose of using newlines is to separate strings into multiple lines. This is useful when:

• Creating multi-line blocks of text
• Breaking code into smaller paragraphs
• Creating line breaks in the output (for example, in Print text in the console)

Example

// 创建一个多行字符串
const text = "这是第一行。\n这是第二行。\n这是第三行。";

// 使用换行符分隔代码段
const code = `
const x = 1;
const y = 2;
console.log(x + y);
`;

// 在输出中创建换行
console.log("第一行\n第二行\n第三行");

Note:

• Different operating systems and environments Different newlines may be used. Always check the target platform's conventions.
• Usage \r Only suitable for older systems or environments compatible with DOS or Windows.
• In cross-platform applications, it is recommended to use \r\n to ensure compatibility.
