Knowra JavaScript JavaScript JavaScript is a high-level programming language standardized as ECMAScript. It runs in web browsers and other environments, supporting interactive pages and server-side applications.
ECMAScript : ECMAScript is the language specification that defines JavaScript’s syntax, types, and behavior. Its evolving standards specify the core language implemented by JavaScript engines.
Dynamic typing : Dynamic typing determines types at runtime rather than requiring declarations that fix them during compilation. JavaScript variables can hold values of different types over their lifetimes.
Document Object Model : The Document Object Model represents a document as a tree of objects that programs can inspect and change. Browser JavaScript commonly updates page content and structure through the DOM.
Brendan Eich : Brendan Eich is a computer programmer who created JavaScript at Netscape in 1995. He designed the language during its brief initial development at Netscape.
Java : Java is a statically typed, class-based programming language that runs on the Java Virtual Machine and other platforms. Despite the similar name, Java is a separate language with different typing and execution models.
JavaScript engine : A JavaScript engine parses and executes JavaScript code, often compiling it to machine code. Engines such as V8 turn JavaScript programs into running instructions.
First-class function : A first-class function can be stored, passed as an argument, and returned like other values. JavaScript functions are values used for callbacks, composition, and event handling.
Node.js : Node.js is a JavaScript runtime built on the V8 engine for applications outside web browsers. It made JavaScript a widely used language for servers, tools, and command-line programs.
Netscape : Netscape Communications was a software company known for the Netscape Navigator web browser. JavaScript originated as a scripting language for Netscape Navigator.
WebAssembly : WebAssembly is a portable binary instruction format designed for efficient execution in web browsers and other environments. It complements JavaScript with a lower-level target for code written in multiple languages.
