JavaScript language overview
JavaScript is a multi-paradigm, dynamic language with types and operators, standard built-in objects, and methods. Its syntax is based on the Java and C languages — many structures from those languages apply to JavaScript as well. JavaScript supports object-oriented programming with object prototypes and classes. It also supports functional programming since functions are first-class objects that can be easily created via expressions and passed around like any other object.
This page serves as a quick overview of various JavaScript language features, written for readers with background in other languages, such as C or Java.
JavaScript is a programming language used primarily to create interactive effects within web browsers. It is one of the core technologies of web development, along with HTML and CSS, and allows for dynamic behavior and interactions on web pages.
Key Features of JavaScript:
-
Dynamic Content:
JavaScript can modify the content and structure of a webpage dynamically without needing to reload the entire page. This is often used for things like updating data, animations, and interactive elements. -
Event Handling:
JavaScript can respond to user interactions such as clicks, keyboard presses, or mouse movements using events. -
Variables and Data Types:
JavaScript supports various data types such as strings, numbers, booleans, arrays, and objects. It allows the use of variables to store data.
