Ace Your Next JavaScript Interview: `this`, `new`, Prototypes, Classes (Part 3) ✨

Explores JavaScript's object-oriented concepts including the `this` keyword's runtime binding behavior, the `new` keyword for object creation, prototypal inheritance chains, ES6 classes as syntactic sugar over prototypes, and composition as an alternative to complex inheritance hierarchies. Covers practical examples showing how `this` depends on call-site context, how prototypes enable property lookup chains, and performance considerations when choosing between instance methods and prototype methods.
