JavaScript Prototype Tutorial - From Zero to Object Oriented Deep Dive
JavaScript Prototype Tutorial - From Zero to Object Oriented Deep Dive.
JavaScript Prototypes explained step-by-step - including the prototype chain, Object.create, the new keyword, and how modern class syntax still uses prototypes under the hood.
In this deep dive, we’ll build the idea from scratch (no confusing definitions first):
✅ Object literals → factory/constructor pattern
✅ Why duplicating methods hurts memory
✅ Sharing methods with Object.create()
✅ The “prototype” property on functions (what it actually is)
✅ How new + this works internally
✅ Converting prototype-based code into modern class syntax
✅ Real example: Array methods (push) coming from Array.prototype (prototype chain)
If you want the next video, comment: "prototype chain" and tell me which part confused you before.
