Learn Full-Stack Development: Part 3 - Mastering Advance JS

Welcome to the Full-Stack Development Series! In this part, we’ll dive deep into Advanced JavaScript. By the end of this 10-day challenge, you'll have mastered essential JavaScript concepts that are pivotal for building powerful, high-performance applications.

---

Day 1: Refreshing JavaScript Foundations

• Topics Covered:

  1. Modern JavaScript Syntax (ES6+):
     • let and const: Block scoping and immutability.
     • Arrow functions: Simplified syntax, implicit return, and this differences.
     • Template literals, default parameters, and shorthand object properties.
  2. JavaScript Runtime:
     • How JavaScript runs in browser and Node.js environments.
     • Event loop basics: Stack, queue, and asynchronous task processing.
  3. Role of the V8 engine and JavaScript performance.

• Task:

  1. Write scripts using let, const, and arrow functions.
  2. Use console.time to measure execution times for synchronous and asynchronous tasks.

---

Day 2: Functions and Closures

• Topics Covered:

  1. Function Declarations vs. Expressions.
  2. Closures: Understanding scope retention and real-world use cases.
  3. Immediately Invoked Function Expressions (IIFE) for scope isolation.

• Task:

  1. Create a closure-based counter with increment, decrement, and reset functionality.
  2. Rewrite a program using an IIFE to avoid global scope pollution.

---

Day 3: Objects and Prototypes

• Topics Covered:

  1. Creating Objects using literals, constructors, and Object.create().
  2. Property descriptors (writable, enumerable, configurable).
  3. Prototypes and the prototype chain.

• Task:

  1. Create a prototype-based object hierarchy.
  2. Implement method overriding in a prototype chain.

---

Day 4: Object-Oriented Programming in JavaScript

• Topics Covered:

  1. Classes in ES6: constructor, instance methods, and static methods.
  2. Inheritance using extends and super.
  3. Private properties using symbols or #.

• Task:

  1. Build a class hierarchy: Vehicle > Car > ElectricCar with overridden methods.
  2. Implement a class with private properties for sensitive data.

---

Day 5: Advanced Array and Object Handling

• Topics Covered:

  1. Destructuring and default values.
  2. Spread and rest operators for merging and copying.
  3. Array methods: map, filter, reduce, find, every, and some.

• Task:

  1. Group an array of numbers into even and odd categories using reduce.
  2. Merge multiple objects using the spread operator.

---

Day 6: Asynchronous JavaScript Basics

• Topics Covered:

  1. Promises: .then, .catch, and .finally.
  2. Async/Await: Cleaner syntax for handling promises.
  3. Error handling with try...catch.

• Task:

  1. Fetch data from an API (e.g., JSONPlaceholder) using Promises and Async/Await.
  2. Create a promise-based function to simulate an API delay.

---

Day 7: Advanced Asynchronous Patterns

• Topics Covered:

  1. Combining Promises with Promise.all and Promise.race.
  2. Microtasks vs. Macrotasks: Understanding event loop priorities.

• Task:

  1. Simulate loading multiple images using Promise.all.
  2. Demonstrate microtask prioritization using queueMicrotask.

---

Day 8: Debugging and Error Handling

• Topics Covered:

  1. Types of errors: Syntax, runtime, and logical.
  2. Debugging tools: Breakpoints, call stack analysis, and variable watches.
  3. Creating custom error classes.

• Task:

  1. Create a custom error class for validating user input.
  2. Debug a sample application using browser DevTools.

---

Day 9: Performance and Memory Management

• Topics Covered:

  1. Memory management basics: Heap, stack, and garbage collection.
  2. Preventing memory leaks.
  3. Optimization techniques:
     • Avoiding excessive DOM manipulation.
     • Using debounce and throttle.
     • Lazy loading and efficient rendering.

• Task:

  1. Profile and optimize an event listener using debounce and throttle.
  2. Use Chrome DevTools to analyze memory usage.

---

Day 10: Currying and Partial Application

• Topics Covered:

  1. Currying: Transforming functions with multiple arguments into a sequence of single-argument functions.
  2. Partial application: Pre-setting some arguments for reuse.

• Task:

  1. Write a curried function to calculate the volume of a box: volume(length)(width)(height).
  2. Create a partially applied function for discount calculation:

   function calculateTotal(price, discount, tax) {
     return price - price * discount + tax;
   }
  

1. Implement reusable curried functions for string manipulation, such as trimming, converting to uppercase, and appending a suffix.

Final Task: Advanced JavaScript Application

• Objective: Build a comprehensive JavaScript-based application:
  1. Use closures, promises, and async/await for functionality.
  2. Implement OOP principles with classes.
  3. Optimize performance using debounce and throttle.
  4. Debug and profile the app for memory and CPU usage.
