Function naming convention

Function's names are formatted in camelCase notation. It’s a best practice to include the verb as a prefix in the function name that tells the purpose of the function.
In JavaScript function is just like a procedure or collection statements of calculating a value or perform a task. We will learn about the functions in detail in the later sections.


              
1234567

            
// Descriptive name of function
function getName(firstName, lastName) {
    return `${firstName} ${lastName}`;
}

const myName = getName('Bob','William');
console.log(myName);
copy

Classes naming convention:

Class is declared with a PascalCase. Class is like a template for creating objects. They encapsulate data with code to work on that data. We will study the classes in detail in later sections.


              
123456789

            
class WebDeveloper {
	constructor(firstName, lastName) {
		this.firstName = firstName;
		this.lastName = lastName;
	}
}

const robinWieruch = new WebDeveloper('Robin', 'Wieruch');
console.log(robinWieruch);
copy

Note:

Classes are very advanced topics and will be covered later, so no exercises for this topic for now.

Summary:

  • Naming convention purpose logic in your code. It is the standard in the JS community.
  • Variables are case-sensitive.
  • Constants are written in UPPERCASE (capital letters).
  • Prefixes are added in the booleans for clarity.
  • Functions names are formatted in camelCase notation.
  • Class is declared with a PascalCase.

Everything was clear?
