Lines

The new line character '\n'

One other special characters in strings is the \n (new line), we use it to represent a new line without having to have a new line in our string.

Also the single and double quote delimited strings can't actually have literal new lines:

let fewlines = "\nHello👏\nThere👏\n";
// Same string but with literal new lines:
let usingLiteral = `
Hello👏
There👏
`;

You can use the literal \n character to split text on each lines:

let splitted = `
Hello👏
There👏
`.split("\n");

console.log(splitted); // ['','Hello👏','There👏', '']
// Note that empty lines becomes empty strings !
