Scoping is a fundamental concept in JavaScript that determines the accessibility and visibility of variables, and functions within a program.

let's delve into the world of scoping.

Scoping

Scoping refers to area of the code where a variable or identifier is defined and accessible.

Types of Scopes

There are two primary types of scopes in JavaScript:

1. Global Scope🌍: The global scope is the outermost scope of a JavaScript program. variable declared in the global scope is accessible from anywhere in the code. JS is also known as the "Window" object in a browser environment.
   example: Just as a country(India) has its own rules, regulations, and laws that apply everywhere within its borders, those laws apply anywhere in the country.

2. Local Scope 🏠: local scope is created when the function is defined. variable can access only inside the function itself. can not access outside of that function.
   example: Just as a state (Maharashtra) has its own rules, regulations, and laws that apply only within its borders, not in another state.

Best Practices🌟

• Use global scope sparingly to avoid naming conflicts and polluting the global namespace.
• Use local scope to encapsulate variables and functions within a function, promoting modularity and reusability🔄.

By mastering scoping in JavaScript, you'll be well on your way to writing more maintainable, efficient, and scalable code!🎉.
