"Before learning frameworks like React or backend technologies like Node.js, it's essential to build a strong understanding of JavaScript fundamentals. A solid foundation makes advanced concepts much easier to learn."
Introduction
During Week-03 of my Full Stack Development learning journey, I focused on understanding the fundamental concepts of JavaScript. Instead of only writing code, I wanted to understand how JavaScript works behind the scenes.
In this week, I learned about variables, hoisting, different types of scope, execution context, call stack, closures, the this keyword, call(), apply(), bind(), module patterns, and clean coding principles like DRY and KISS.
In this blog, I'll explain each concept in a simple and beginner-friendly way with examples.
