ECMAScript is a standard for scripting languages, including JavaScript, JScript, and ActionScript. It is also best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. It is standardized by Ecma International in the document ECMA-262.ECMAScript is commonly used for client-side scripting on the World Wide Web, and it is increasingly being used to write server-side applications and services using Node.js and other runtime environments.

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. As of 2023, 98.7% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries. All major web browsers have a dedicated JavaScript engine to execute the code on users' devices.

TypeScript is a free and open-source high-level programming language developed by Microsoft that adds static typing with optional type annotations to JavaScript. It is designed for the development of large applications and transpiles to JavaScript.[5] Because TypeScript is a superset of JavaScript, all JavaScript programs are syntactically valid TypeScript, except additional type-check.

JSX (JavaScript Syntax Extension and occasionally referred as JavaScript XML) is a JavaScript extension that allows creation of DOM trees using an XML-like syntax. Initially used by Meta for use with React, JSX has been adopted by multiple web frameworks. Being a syntactic sugar, JSX is generally transpiled into nested JavaScript function calls structurally similar to the original JSX.

A single-page application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of a web browser loading entire new pages. The goal is faster transitions that make the website feel more like a native app. In a SPA, a page refresh never occurs; instead, all necessary HTML, JavaScript, and CSS code is either retrieved by the browser with a single page load or the appropriate resources are dynamically loaded and added to the page as necessary, usually in response to user actions.

While writing web pages and apps, most common things are manipulating the document structure and making network requests in some way. This is usually done by using the Document Object Model (DOM), a set of APIs for controlling HTML and styling information that makes heavy use of the Document object and XMLHttpRequest Object. In this courses we'll look at how to use the DOM and XMLHttpRequest in detail, along with some other interesting APIs.

Node.js is a cross-platform, open-source server environment that can run on Windows, Linux, Unix, macOS, and more. Node.js is a back-end JavaScript runtime environment, runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser.

Representational state transfer (REST) is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of an Internet-scale distributed hypermedia system, such as the Web, should behave. The REST architectural style emphasises the scalability of interactions between components, uniform interfaces, independent deployment of components, and the creation of a layered architecture to facilitate caching of components to reduce user-perceived latency, enforce security, and encapsulate legacy systems.
