How to create a multiline string in JavaScript?

In JavaScript, a string is a sequence of characters containing letters, numbers, and special characters. There are three ways we can create strings in JavaScript.

The first way to create a string is to use single quotes below.

let string = 'Hello, this is a string using single quote!'; 

The second way to create a string is to use double quotes, as shown below.

let string = "Hello, this is a string using double quote!"; 

The third method introduced in the ES6 version of JavaScript is to use backticks.

let string = `Hello, this is a string using back quotes!`; 

So there is a different way to create a multi-line string whenever we use backticks, single quotes and double quotes. We will learn all the methods one by one.

Create a multi-line string with backticks

When we create a string using backtick (`), we need to write the string in new lines, thus creating a multi-line string.

grammar

Users can create multi-line strings using backticks according to the following syntax.

let string = `one line
second line
Third line`; 

In the above syntax, we added the sequence of characters between backticks.

Example 1

In the example below, the string variable contains a multi-line string, and we use backticks to create the multi-line string.

In the output, the user can observe the multiple lines we wrote within the backticks.

let string = `This is first line! 
This is the second line!
This is the third line!
This is the fourth line!`
console.log(string);

Create multi-line strings with single and double quotes

When we create a string using single quotes or double quotes, we need to use '

' characters to create multi-line strings. In the '

' character, '\' represents the escape character and 'n' represents the newline character.

grammar

Users can create multi-line strings using the "

" escape characters according to the following syntax.

let string = 'Abcd ' + 'efg '; 

In the above syntax, users can see how we can use "

" characters and single quotes to create a multi-line string.

Example 2

In the following example, we use the " " operator to concatenate multiple strings. Additionally, we use single quotes to create strings.

In the output, we can see the first, second, third and fourth in different lines.

let string = 'One ' +
 'Second ' +
 'Third ' +
 'Fourth ';
console.log(string); 

Example 3

In the following example, we use double quotes to create the string. Additionally, we use the "

" escape characters to create a string across multiple lines.

let string = "One " +
"Second " +
"Third " +
"Fourth ";
console.log(string);  

In this tutorial, we learned two ways to create multi-line strings. The first method uses backticks and the other method uses "

" escape characters with single and double quotes. It is recommended to use backticks as we can also add variables between strings while using them.
