In JavaScript, strings are typically defined within single (') or double (") quotes. However, these methods don't allow for easy creation of multiline strings. This tutorial will show you how to create multiline strings using backticks (```) in JavaScript.

1var singleLine = 'This is a single line string';
2console.log(singleLine);
3
4var multiLine = `This is a
5multiline
6string`;
7console.log(multiLine);

The output of the above code will be:

1This is a single line string
2This is a
3multiline
4string

Template Literals

Backticks are used in JavaScript to define template literals, a type of string that can span multiple lines and include embedded expressions.

1var name = 'John';
2var greeting = `Hello, ${name}!
3Welcome to our website.`;
4console.log(greeting);

This will output:

1Hello, John!
2Welcome to our website.

Escape Sequences

Alternatively, you can create multiline strings in JavaScript using escape sequences. The newline character (\n) is used to insert a new line.

1var multiLine = 'This is a\nmultiline\nstring';
2console.log(multiLine);

This will output:

1This is a
2multiline
3string

Browser Compatibility

All modern browsers support template literals and escape sequences for creating multiline strings in JavaScript.
