Encapsulation is one of the core principles of Object-Oriented Programming (OOP). It means bundling the data (properties) and the methods (functions) that work on that data into a single unit, usually an object. But beyond just grouping, encapsulation controls how data inside an object is accessed or modified. It hides the internal details from the […]

JavaScript’s object system is unique compared to many classical languages because it is based on prototypical inheritance. Unlike classical inheritance where classes inherit from other classes, JavaScript objects inherit directly from other objects through a prototype chain. This model allows objects to share properties and methods by linking to a prototype object, which can then

Inheritance is a core concept in object-oriented programming (OOP) that allows one class to inherit properties and methods from another. In JavaScript, inheritance lets developers create new classes that build upon existing ones, promoting code reuse and logical structure. When a class inherits from another, it can access and use the parent’s features while also

JavaScript classes are a way to create objects and organize code in a clean, structured way. Introduced in ES6, classes provide a clear and straightforward syntax to build objects, hiding the prototype-based inheritance model underneath. Although JavaScript still uses prototypes internally, classes give programmers a more familiar, classical style for object-oriented programming. This makes it

JavaScript’s object-oriented programming is built on a unique and powerful concept called prototypes. Unlike many classical languages that use classes, JavaScript uses prototypes to enable objects to inherit properties and methods from other objects. This system allows objects to share behavior efficiently without duplicating code for each instance. Understanding prototypes is key to mastering how

In JavaScript, constructors are special functions designed to create new objects. They serve as blueprints, allowing programmers to define the structure and behavior of an object once, then generate many instances from that same blueprint. This concept is fundamental in object-oriented programming, where managing many similar objects efficiently is a core need. Constructors give us

IndexedDB is a powerful built-in browser database that lets web applications store large amounts of structured data. Unlike simpler web storage solutions like localStorage or sessionStorage, IndexedDB supports complex objects and transactions, making it ideal for applications that require offline capabilities, such as games, note-taking apps, or any system needing persistent data beyond just simple

Objects are at the heart of JavaScript and are essential to understanding how the language models real-world things. Simply put, an object is a container that holds related data and functions together. These containers represent entities with properties (describing characteristics) and methods (actions they can perform). JavaScript’s object system is flexible, allowing developers to create

Session storage is a built-in web storage feature in JavaScript that allows websites to save data for the duration of a browser tab session. Unlike localStorage, which keeps data even after closing and reopening the browser, sessionStorage only holds information as long as the tab or window remains open. Once the user closes the tab,

Object-Oriented Programming (OOP) is a way of writing code that models real-world things or ideas as objects. These objects group together data (called properties) and actions (called methods) that belong together. This method of programming helps us organize code clearly and makes it easier to manage complexity by thinking in terms of objects rather than
