Object Oriented Programming with JavaScript for Beginners

Explore JavaScript primitive data types—boolean, number, string, null, and undefined—and how typeof and double versus triple equals reveal value and type comparisons.

Explore JavaScript reference types by creating objects with new and literals, manipulating properties, dereferencing to null, and understanding memory location, pointers, and garbage collection.

Learn to declare functions (declaration and expression), pass them as values, and use the arguments object. Understand function overloading limits and implement numeric sorting with a custom comparator.

See how JavaScript objects reduce tight coupling by using this and object methods. Learn to change context with call, apply, and bind for flexible, dynamic behavior.

Learn how JavaScript constructors initialize objects using the new operator, define properties and methods, and create multiple instances with parameterized values.

Explore how JavaScript creates a function object and its prototype, demonstrates __proto__, and shows property lookup through the prototype chain and basic inheritance.

Explore prototype-based inheritance in JavaScript, showing how to link employee and manager objects, extend prototypes, and print names with a shared getName method.
