JavaScript Variable Scopes

Here are some key points about variable scopes in JavaScript:

1. Global Scope:
   • Variables in the global scope can be accessed from anywhere in your code.
2. Function Scope:
   • Variables in the function scope can only be accessed within the function where they are declared.
3. Block Scope:
   • Variables in the block scope can only be accessed within the block (like within {}) where they are declared.

Key Points:

• Global Scope: Accessible everywhere in the code.
• Function Scope: Accessible only within the function.
• Block Scope: Accessible only within the block.
