What is JavaScript?
JavaScript is a high-level, versatile, and widely used programming
language that is primarily known for its role in building dynamic and
interactive web pages. It is a client-side scripting language, meaning
that it is executed on the user's web browser rather than on a web
server. JavaScript enables developers to add interactivity, manipulate
the Document Object Model (DOM), and create dynamic content within web
browsers.
Key features and aspects of JavaScript include:
-
Client-Side Scripting:JavaScript is primarily used
for client-side scripting, allowing developers to create dynamic and
interactive user interfaces in web browsers. It can respond to user
actions, handle events, and modify the content and structure of web
pages in real-time.
-
Dynamic Typing:JavaScript is a dynamically typed
language, meaning that variable types are determined at runtime.
This flexibility allows for more versatile coding but requires
careful attention to type-related issues during development.
-
Prototypal Inheritance: JavaScript uses a
prototypal inheritance model, where objects can inherit properties
and methods directly from other objects. This provides a flexible
and dynamic way to create and extend object hierarchies.
