Lexical Scoping in JavaScript
Lexical scoping is the scoping mechanism used in JavaScript. It means that the scope of a variable is determined by its position within the source code. This allows for nested functions to have access to variables defined in their outer scope.
Key Points:
- In lexical scoping, the scope of a variable is defined by its location within the source code.
- JavaScript uses lexical scoping, which means that variables are accessed based on their position in the code, not the runtime stack.
- This allows for nested functions to access variables from their outer scope.
- Lexical scoping helps in avoiding variable conflicts and provides a clear structure to the code.
Overall, lexical scoping is a fundamental concept in JavaScript that helps in organizing and managing variables effectively within the code.
