| object oriented js interview questions: JavaScript Interview Questions and Answers Navneet Singh, I can provide JavaScript interview questions and answers. Here are some common JavaScript interview questions along with sample answers: What is JavaScript? JavaScript is a high-level, interpreted programming language that is primarily used to add interactivity and dynamic behaviour to web pages. It is commonly used for client-side web development and can also be used for server-side development using frameworks like Node.js. What are the key features of JavaScript? Some key features of JavaScript include: Dynamic typing: Variables can hold values of any data type without explicit declaration. Prototype-based inheritance: Objects can inherit properties and methods from other objects. First-class functions: Functions are treated as first-class citizens, allowing them to be passed around as arguments and returned from other functions. Event-driven programming: JavaScript is well-suited for handling events such as user interactions and asynchronous operations. Support for object-oriented, functional, and procedural programming paradigms. What are the differences between == and === in JavaScript? The == operator checks for equality of values after performing type coercion, while the === operator checks for strict equality of values without type coercion. For example: 5 == '5' evaluates to true because the values are equal after type coercion. 5 === '5' evaluates to false because the values are of different types. What is closure in JavaScript? A closure is a function that retains access to variables from its parent scope even after the parent function has finished executing. Closures are created whenever a function is defined within another function and has access to variables from the outer function's scope. Explain the concept of hoisting in JavaScript. Hoisting is a JavaScript behaviour where variable and function declarations are moved to the top of their containing scope during the compilation phase. This means that variables and functions can be used before they are declared. However, only the declarations are hoisted, not the initializations. What are arrow functions in JavaScript? Arrow functions are a concise way to write anonymous functions in JavaScript. They provide a more compact syntax compared to traditional function expressions and lexically bind this value. For example: These are just a few examples of JavaScript interview questions. Depending on the role and level of expertise required, interview questions can cover a wide range of topics including DOM manipulation, asynchronous programming, ES6 features, and more. |

| object oriented js interview questions: JavaScript Object Programming Martin Rinehart, 2015-12-30 This brief book explains the advantages of the object model, inheritance, both classical and prototypical, and shows how these concepts can be implemented in JavaScript. It also shows how object programming (OP) opens a new world of design possibilities that go far beyond inheritance. This book will help the intermediate JavaScript programmer learn to use both types of inheritance. For classical inheritance, it is accompanied by a substantial online system (a windowing UI library) that shows classical inheritance at its best. The same system shows how OP capabilities can eliminate much of the need for inheritance. For experienced JavaScript programmers, this book shows why most of the old views of JavaScript's inheritance have not done it justice. JavaScript classes inherit from JavaScript's prototypes, a fact that makes JavaScript's prototypes, when used correctly, functional equivalents to C++ classes(not to prototypes in true prototypical languages, like Self). JavaScript's object programming (not inheritance) is what separates it from classical OOP languages like C++ and Java. Most important, basing inheritance on JavaScript's prototypal chain is possible, but is not the best choice for prototypal inheritance or classical inheritance. What You'll Learn What are objects, JavaScript objects and object programming What is and how to use inheritance and JavaScript inheritance as well as inheritance alternatives How to design for JavaScript What are and how to use OO principles in JavaScript How to use Constructors with JavaScript and more AudienceThis book is for both intermediate and advanced JavaScript and Web development programmers. However, any programmer will understand the concepts and any JavaScript programmer should understand all of the concepts in this book. The code there is shows examples of the concepts discussed. |

| object oriented js interview questions: Head First HTML5 Programming Eric Freeman, Elisabeth Robson, 2011-10-06 HTML has been on a wild ride. Sure, HTML started as a mere markup language, but more recently HTML’s put on some major muscle. Now we’ve got a language tuned for building web applications with Web storage, 2D drawing, offline support, sockets and threads, and more. And to speak this language you’ve got to go beyond HTML5 markup and into the world of the DOM, events, and JavaScript APIs. Now you probably already know all about HTML markup (otherwise known as structure) and you know all aboutCSS style (presentation), but what you’ve been missing is JavaScript (behavior). If all you know about are structure and presentation, you can create some great looking pages, but they’re still just pages. When you add behavior with JavaScript, you can create an interactive experience; even better, you can create full blown web applications. Head First HTML5 Programming is your ultimate tour guide to creating web applications with HTML5 and JavaScript, and we give you everything you need to know to build them, including: how to add interactivity to your pages, how to communicate with the world of Web services, and how to use the great new APIs being developed for HTML5. Here are just some of the things you’ll learn in Head First HTML5 Programing: Learn how to make your pages truly interactive by using the power of the DOM. Finally understand how JavaScript works and take yourself from novice to well-informed in just a few chapters. Learn how JavaScript APIs fit into the HTML5 ecosystem, and how to use any API in your web pages. Use the Geolocation API to know where your users are. Bring out your inner artist with Canvas, HTML5’s new 2D drawing surface. Go beyond just plugging a video into your pages, and create custom video experiences. Learn the secret to grabbing five megabytes of storage in every user’s browser. Improve your page’s responsiveness and performance with Web workers. And much more. |
