You've encountered a bug in your JavaScript code where a variable is not retaining an expected value within a nested function. What feature of JavaScript should you explore to troubleshoot this issue?
- Lexical Scoping
- Hoisting
- IIFE (Immediately Invoked Function Expression)
- Event Delegation
To troubleshoot the issue of a variable not retaining an expected value within a nested function, you should explore the concept of lexical scoping. Lexical scoping (also known as static scoping) means that the scope of a variable is determined by its location within the source code, and nested functions have access to variables from their containing (parent) functions. This understanding will help you identify and fix the problem.
