Basic Syntax and Structure:
- Data Types: Number, String, Boolean, Object, Array, Null, Undefined, Symbol, BigInt.
- Variables: Declaration with var, let, and const.
- Operators: Arithmetic, comparison, logical, bitwise, etc.
- Control Structures: if, else, switch, loops (for, while, do-while)

Functions:
- Function Declarations: Traditional function syntax.
- Function Expressions: Anonymous functions, immediately invoked function expressions (IIFE).
- Arrow Functions: Shorter syntax with lexical this.
- Higher-Order Functions: Functions that take other functions as arguments or return functions.

- Destructuring: Extracting values from arrays or objects into distinct variables.
DOM Manipulation:
- Selecting Elements: Methods like getElementById, querySelector, querySelectorAll.
- Modifying Elements: Changing attributes, styles, content.
- Event Handling: Adding event listeners for user interactions.
Event Loop and Asynchronous Programming:
- Event Loop: Understanding how JavaScript handles asynchronous operations.
- Callbacks: Functions passed as arguments to be executed later.
- Promises: Handling asynchronous operations with then and catch.
- Async/Await: Syntactic sugar for working with promises.
Scope and Closures:
- Scope: Understanding global, function, and block scope.
- Closures: Functions that retain access to their lexical scope.
ES6+ Features:
- Template Literals: String interpolation with backticks.
- Default Parameters: Setting default values for function parameters.
- Rest and Spread Operators: Collecting and spreading elements.
- Modules: Importing and exporting code between files.
Error Handling:
- Try-Catch: Handling exceptions and errors.
- Throwing Errors: Custom error handling.
JavaScript Objects and Prototypes:
- Prototypal Inheritance: Understanding prototype chains.
- Object-Oriented Programming: Using classes and constructors.
APIs and AJAX:

- Integration Testing: Testing combined parts of an application.
Performance Optimization:
- Minification and Compression: Reducing file sizes.
- Lazy Loading: Loading resources only when needed.
- Debouncing and Throttling: Controlling function execution rate.
Security:
- Cross-Site Scripting (XSS): Preventing malicious code injection.
- Cross-Site Request Forgery (CSRF): Protecting against unauthorized actions.
Web Components:
- Custom Elements: Creating reusable custom HTML elements.
- Shadow DOM: Encapsulating styles and markup.
Progressive Web Apps (PWAs):
