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 !
