JavaScript Special Characters

In JavaScript, we can insert special characters into a text String by using the backslash (\) symbol. Various special characters such as single quotes, double quotes, ampersands, new lines, tabs, backspaces, form feeds, and more can be included by placing the backslash right before the characters.

Below is a compilation of characters that can be appended to a string in JavaScript:

Name	Special Character
Single quote	\'
Double quote	\"
Ampersand	\&
Newline	\n
`Tab`	\t
Backslash	\\
Carries return	\r
Backspace	\b
Form feed	\f
Vertical tab	\v

Before diving into how to add special characters in a string, let's understand what the strings are in JavaScript.

JavaScript String

Within JavaScript, a String represents a collection of characters, symbols, and digits. It encompasses various characters, symbols, and numeric values. Illustrations include "abc", "abc@!#", and "abc@12345".

The String data type is widely utilized in programming languages. Similar to other data types, Strings have their own memory allocation. In TestComplete, Strings are depicted as OLE-compatible variants.

Strings are identified as a series of characters enclosed within a corresponding set of quotation marks. These quotation marks can be single (') or double ("); both are viewed equally and are recognized as containing a String value.

Below are a few instances of valid strings:

Example


str1 = " Lorem Ipsum is simply dummy text.";  

str2 = ' Lorem Ipsum has been the industry's standard dummy text ever since the 1500s.';  

str3 = "Opps!?' - there is an error.";  

str4 = '"Great." - Data is updated successfully.'

The String object is accessible in all scripting languages that are supported, enabling users to manipulate and work with string values regardless of the programming language they have opted for.

Now, let's explore the process of adding special characters to a String:

Insert Special Characters to a String in JavaScript

Special characters can be included in a String by utilizing the backslash (\) symbol. Various special characters like apostrophes, line breaks, quotes, and other special characters can be inserted.

Consider the below example:

Example


<html lang="en">

<head>

  <title>JavaScript Special Character</title>

</head>

<body>

    <script type="text/javascript">

        document.write("This is how we can write \"double quote\" special character.");

    </script>

</body>

</html>

Let's see another example:

Example


function myFunction()

{

  let aString = "Dummy String";

  console.log("The string is " + aString.length + " character(s) long.");

  console.log("The string is " + aqString.GetLength(aString) + " character(s) long.");

}

Output:

Output


The String is 12 character(s) long.

Therefore, it is possible to include any special characters within our String data.
