- Analyze variable scope and lookup to predict how functions access and modify variables
- Apply hoisting rules to explain undefined values and choose clear declaration styles
- Use let and const to enforce block scope and prevent reassignment and hoisting pitfalls
- Implement callbacks and closures to create factory functions and encapsulate private data
- Differentiate value vs reference behavior to avoid unintended mutation in objects and arrays
- Write functional data transforms using map, filter, forEach, and reduce on arrays and objects
- Build asynchronous flows with the event loop, Promises, and async/await including error handling

WHY I WROTE THIS COURSE
This is for those familiar with the basics of JavaScript and looking to advance their knowledge and really understand how the language works. We'll cover topics that are essential to help you read, understand, and write better code. Before starting, you should be familiar with the basics of variables, functions, and loops in JavaScript.
This course will enable you to master JavaScript interview questions that stump most developers. You'll be able to talk intelligently about the fundamentals of the language and about common design patterns.
