JavaScript Special Characters

JavaScript allows the use of special characters within strings and regular expressions. Here are some commonly used special characters in JavaScript:

1. Backslash (): Used as an escape character to represent special characters or sequences. For example, \n represents a newline character, \t represents a tab character, and \" represents a double quote character within a string.
2. Single Quote (‘) and Double Quote (“): Used to delimit string literals. You can use either single quotes or double quotes to define strings in JavaScript.
3. Newline (\n): Represents a line break or a new line character. It is commonly used within strings to create multi-line text.
4. Tab (\t): Represents a horizontal tab character. It is often used within strings to create an indentation effect.
5. Carriage Return (\r): Represents a carriage return character. It is commonly used in conjunction with newline characters (\r\n) to represent line breaks in Windows-style text.
6. Backspace (\b): Represents a backspace character. It is used to remove the previous character from a string.
7. Null (\0): Represents the null character. It is used to terminate strings in some situations.
8. Unicode Escape (\uXXXX): Represents a Unicode character using its hexadecimal code point. For example, \u00A9 represents the copyright symbol “©”.

These are just a few examples of special characters in JavaScript. It’s important to understand their usage and how to properly escape or include them within strings or regular expressions.
