Operator Precedence Table This table ranks JavaScript operators by their precedence, with the higher-precedence operators (executed first) at the top. Operator Precedence Operator Description Associativity Example 1 () Grouping L -> R (expression) 2 . Member of object L ->…
In JavaScript, reserved keywords are terms that are set aside by the language for its internal use. These words cannot be used as identifiers (like variable names, function names, etc.). Using them as identifiers can result in errors or unexpected…
JavaScript syntax refers to the set of rules that defines how JavaScript code is written and structured. Understanding JavaScript syntax is crucial for writing correct and efficient programs. This tutorial will cover the most important aspects of JavaScript syntax, including…
Mixins in JavaScript are a flexible way to reuse code across multiple classes without using traditional inheritance. A mixin is an object or function that provides reusable methods, which can be mixed into other classes. Mixins help share behavior among…
Template literals (also called template strings) in JavaScript are a powerful feature introduced in ES6 (ECMAScript 2015). They allow you to create multi-line strings, embed variables and expressions into strings, and make string concatenation easier and more readable. In this…
In JavaScript, classes are a way to define blueprints for creating objects. While JavaScript has been an object-oriented language from the start, ES6 (ECMAScript 2015) introduced the class keyword, which simplifies working with object-oriented programming (OOP) concepts such as inheritance,…
Encapsulation is a key concept in object-oriented programming (OOP) that focuses on bundling the data (properties) and the methods (functions) that operate on that data into a single unit, usually a class or an object. Encapsulation helps in controlling access…
Inheritance is a core concept in object-oriented programming (OOP) that allows one class to inherit the properties and methods of another class. In JavaScript, inheritance enables code reuse and provides a way to create hierarchical class structures where subclasses (derived…
Abstraction is one of the key principles of object-oriented programming (OOP). It helps in hiding complex implementation details from the user and exposes only what is necessary for interacting with an object or system. In JavaScript, abstraction allows you to…
Polymorphism is a fundamental concept in object-oriented programming (OOP), which allows different objects to be treated in a similar way based on shared behaviors or interfaces. In JavaScript, polymorphism is often achieved through inheritance and method overriding, where objects of…
