JavaScript Function Arguments | CODiiN Tutorial 🧑‍💻
👉 Welcome to CODiiN, your premier software training institute in Kochi, Kerala! In this tutorial, we will explore JavaScript function arguments, a fundamental concept that enables you to pass data to functions for processing.

🔍 Understanding Function Arguments
In JavaScript, function arguments are the values that you pass into a function when you invoke it. These arguments can be of any data type, including numbers, strings, objects, arrays, and even other functions. The primary purpose of function arguments is to allow you to customize the behavior of a function based on the inputs it receives.

📚 Declaring Function Arguments
You can declare function arguments in the parentheses of the function definition.

🌟 Types of Function Arguments
Required Arguments:

These are mandatory parameters that must be provided when calling the function.
Optional Arguments:

These parameters can be omitted when calling the function. If omitted, they will be undefined.
Rest Parameters:

The rest parameter syntax allows you to represent an indefinite number of arguments as an array. This is useful when the number of arguments is not fixed.
⚙️ Accessing Arguments
Inside a function, you can access the arguments using the arguments object, which is an array-like object available to all non-arrow functions. However, note that the arguments object does not exist in arrow functions.

🚫 Important Notes
Data Types: JavaScript is a dynamically typed language, which means you can pass arguments of any type, and the function can handle them accordingly.
Argument Length: You can check the number of arguments passed to a function using arguments.length.
