How to implement line breaks in nodejs (4 methods)

Line breaks in Node.js can be achieved in a variety of ways, depending on your operating system and editor of choice, as well as your coding style and preferences.

Here are some common ways:

1. Use \n

In Node.js, \n is a special character sequence, which Represents a newline character (line feed), which can be used in strings.

Sample code:

console.log('Hello\nworld');

Output:

Hello
world

2. Using template string

ES6 introduced template string (template string) Syntax, it supports direct line wrapping of multi-line strings, and variables can be used in it.

Sample code:

const name = 'Alice';
const message = `Hello
${name}
!`;
console.log(message);

Output:

Hello
Alice
!

3. Use the "ending space\" syntax

In JavaScript, if If a line of code ends with "end of line space\", it will be regarded as part of the multi-line code, and can be parsed normally even if the next line is not indented.

Sample code:

console.log('Hello \
world');

Output:

Hello world

Note that if there is indentation, you need to add a space before "\":

console.log('Hello \
  world');

Output:

Hello   world

4. Using arrays and join

Since newlines can be used directly in arrays, and the join method of arrays can connect multiple elements into a string, we can Take advantage of these features to implement multiline strings.

Sample code:

const lines = [
  'line 1',
  'line 2',
  'line 3',
];
console.log(lines.join('\n'));

Output:

line 1
line 2
line 3

Regardless of the method used, Node.js can correctly parse multiple lines as long as newlines are inserted correctly in the code String. Which method you choose depends on your coding style and preferences.
