In this article, I will introduce how to add line breaks and tabs in a string with JavaScript.

Add line breaks and tabs

Below is a sample with line breaks and tabs in the string.

//Line breaks
let str = 'Hello\nWorld!';


let str = 'Hello\tWorld!';

"Hello  World!"

Special characters are entered in the form of "\ + characters" in the parts that are replaced with line breaks and tabs at the time of output.
This is called an escape sequence, and it is a character string that represents a special character prepared in advance on the JavaScript side.
