How to write a newline statement in js

The newline statement in JavaScript is written by adding a backslash () at the end of the line of code. The backslash must be placed at the end of the line of code. The split line cannot contain statement terminators. Spaces need to be added immediately after the parentheses. Indentation does not affect execution but improves readability.

How to write newline statements in JavaScript

Newline statements

In JavaScript, newline statements are used to break code into multiple lines, making it easier to read and maintain.

Writing

In JavaScript, you can write a line break statement by adding a backslash () at the end of a line of code:

<code class="javascript">console.log('Hello' +
  ' World');</code>

Example

The following code demonstrates how to use a newline statement:

<code class="javascript">// 分成多行的 longString 变量
const longString = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. ' +
  'Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. ' +
  'Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ' +
  'ut aliquip ex ea commodo consequat.';

console.log(longString);</code>

Note:

• Backslash() must be placed at the end of the line of code.
• The separated lines cannot contain any statement terminator (such as semicolon).
• If a newline character immediately follows a parenthesis, square bracket, or curly brace, you need to add a space before the backslash.
• Indentation does not affect the execution of JavaScript, but it can make the code more readable.
