What Are JavaScript Multiline Strings?

JavaScript is a versatile programming language used for web development. One of the essential features of JavaScript is its ability to handle strings, which are sequences of characters. In this blog post, we will explore a specific type of string called multiline strings in JavaScript.


A multiline string, also known as a template literal, is a string that spans across multiple lines without the need for escape characters. In traditional JavaScript strings, line breaks need to be manually added using the ‘
‘ escape sequence. However, with multiline strings, line breaks are preserved automatically.


To create a multiline string in JavaScript, you can use template literals, denoted by backticks (` `) instead of single or double quotes. Here’s an example:

const message = `This is a
multiline string
in JavaScript.`;

In the above code, the backticks allow us to write the string across multiple lines without the need for escape characters. The resulting string will include the line breaks as they are.


There are several benefits of using multiline strings in JavaScript:

  • Improved Readability: Multiline strings make the code more readable, especially when dealing with long strings or when string concatenation is required.
  • Easy Variable Interpolation: With template literals, you can easily insert variables or expressions within the string by using the ${} syntax. This feature, known as string interpolation, simplifies string manipulation.
  • Preserved Formatting: Multiline strings preserve the formatting, including indentation and line breaks, making it ideal for generating formatted text or templates.


Let’s look at a few examples to demonstrate the usage of multiline strings:

// Example 1: Variable Interpolation
const name = 'John';
const greeting = `Hello, ${name}!
How are you today?`;


// Example 2: Formatted Text
const formattedText = `Name: ${name}
Age: 25
Address: 123 Main St.`;


In the first example, we use variable interpolation to include the value of the ‘name’ variable within the string. This allows us to create personalized greetings dynamically.

The second example showcases how multiline strings can be used to generate formatted text. The resulting string maintains the line breaks and indentation, making it easier to read and understand.


Multiline strings, or template literals, provide a convenient way to work with strings that span across multiple lines in JavaScript. They enhance code readability, simplify string manipulation with variable interpolation, and preserve formatting. Consider using multiline strings in your JavaScript projects to make your code more expressive and maintainable.
