2. Global Scope
3. Local (Function) Scope
4. Block Scope
5. Lexical Scope
Lexical scope, also known as static scope, determines the accessibility of variables based on their location in the source code. When a function is defined, it captures the scope in which it was created. This means that functions can access variables from their containing scope, even if they are called in a different scope.
7. Scope Chain
Shadowing occurs when a variable in an inner scope has the same name as a variable in an outer scope. The inner variable "shadows" the outer one, making it temporarily inaccessible. Understanding shadowing is essential to prevent unexpected behavior in your code.
