Naming conventions

In JavaScript, naming conventions refer to a set of rules and guidelines that developers follow to name variables, functions, and other identifiers. Following a consistent naming convention makes the code more readable, maintainable, and easier to understand for other developers.

Here are some common naming conventions in JavaScript:

1. Camel Case: It's a convention where the first word is in lower case and the subsequent words start with uppercase letters. For example, firstName, totalMarks, fullName, etc.

2. Pascal Case: It's a convention where the first letter of each word is capitalized, and there are no spaces between words. For example, FirstName, TotalMarks, FullName, etc.

3. Snake Case: It's a convention where words are separated by underscores, and all the letters are in lowercase. For example, first_name, total_marks, full_name, etc.

4. Kebab Case: It's a convention where words are separated by hyphens, and all the letters are in lowercase. For example, first-name, total-marks, full-name, etc.

In addition to these conventions, there are some naming rules that you should follow while naming variables and functions in JavaScript:

1. Names should start with a letter or an underscore (_), but not with a number.

2. Names can contain letters, numbers, and underscores (_), but not special characters.

3. Names are case-sensitive. For example, firstName and FirstName are two different variables.

4. Names should be descriptive and meaningful, indicating the purpose of the variable or function.

By following these naming conventions and rules, you can write more readable and maintainable code in JavaScript.
