"JavaScript (), often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS."
Dive into the programming language used to create interactive and dynamic web pages.
Syntax: The basic rules and structure of the JavaScript language, including variables, data types, and functions.
Control flow: The order in which statements are executed in a JavaScript program, including loops and conditional statements.
JavaScript objects: The various kinds of objects in JavaScript, including built-in objects like arrays and strings, as well as custom objects.
Functions: The behavior of functions in JavaScript, including anonymous functions, closures, and the call and apply methods.
DOM manipulation: The manipulation of the Document Object Model (DOM) in JavaScript to change the content and behavior of web pages.
Event handling: How to respond to user actions or events in JavaScript, such as button clicks.
Asynchronous programming: How JavaScript handles asynchronous tasks, such as fetching data from an API or communicating with a server.
Error handling: How to handle errors and exceptions in the code, including try-catch statements.
Regular expressions: The use of regular expressions in JavaScript to match patterns in strings.
ECMAScript standards: The different versions of JavaScript and their features and updates.
Debugging: The tools and techniques for debugging and troubleshooting JavaScript code.
Testing: The various approaches to testing JavaScript code, including unit testing, integration testing, and end-to-end testing.
Libraries and frameworks: The popular JavaScript libraries and frameworks, including React, Angular, and jQuery.
Interoperability: How JavaScript can interact with other programming languages and technologies, such as JSON, Ajax, and Node.js.
Security: How to write secure JavaScript code and avoid common security pitfalls, such as cross-site scripting (XSS) and injection attacks.
ES5 (ECMAScript 5): It is a version of JavaScript released in 2009 by the ECMAScript organization.
ES6 (ECMAScript 2015): It is a version of JavaScript released in 2015 and introduced many new features to the language.
TypeScript: It is a superset of JavaScript developed by Microsoft that adds optional static typing and several other features to the language.
ReactJS: It is a popular JavaScript library used for building user interfaces and is maintained by Facebook.
Vue.js: It is a progressive JavaScript framework used for building user interfaces and is popular among front-end developers.
AngularJS: It is a robust JavaScript framework used for building complex web applications and was first released in 2010.
Node.js: It is a JavaScript runtime built on V8 engine used for building server-side applications.
jQuery: It is a popular JavaScript library used for DOM manipulation, event handling and providing animations effects.
Redux: It is a predictable state container, used for managing the state of large JavaScript applications.
Ember.js: It is a comprehensive JavaScript framework suited for building scalable, single-page web applications.
Backbone.js: It is a lightweight JavaScript library that provides useful features such as models and events for building small-scale web applications.
Three.js: It is a cross-browser JavaScript library used for creating 3D animations and webgl graphics.
D3.js: It is a powerful data visualization JavaScript library used for creating complex data visualizations.
"As of 2023, 98.7% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries."
"JavaScript, alongside HTML and CSS, is one of the core technologies of the World Wide Web."
"JavaScript is a high-level, often just-in-time compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object-orientation, and first-class functions."
"It is multi-paradigm, supporting event-driven, functional, and imperative programming styles."
"It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM)."
"The ECMAScript standard does not include any input/output (I/O), such as networking, storage, or graphics facilities."
"In practice, the web browser or other runtime system provides JavaScript APIs for I/O."
"The most popular runtime system for this usage is Node.js."
"Although Java and JavaScript are similar in name, syntax, and respective standard libraries, the two languages are distinct and differ greatly in design."
"All major web browsers have a dedicated JavaScript engine to execute the code on users' devices."
"Just-in-time compiled languages, like JavaScript, are often used to optimize runtime performance."
"JavaScript was influenced by programming languages such as Self and Scheme."
"JavaScript is a prototype-based object-oriented programming language."
"JavaScript is commonly used for webpage behavior, often incorporating third-party libraries."
"JavaScript engines were originally used only in web browsers but are now core components of some servers and a variety of applications."
"The World Wide Web comprises HTML, CSS, and JavaScript as its core technologies."
"Yes, JavaScript can be used for server-side applications, with Node.js being a popular runtime for this purpose."
"The ECMAScript standard ensures compatibility and provides guidelines for implementing JavaScript."
"No, JavaScript itself does not have built-in support for networking or graphics. The web browser or other runtime system provides JavaScript APIs for such functionality."
