JavaScript is a lightweight and object-oriented scripting language used to create dynamic HTML pages with interactive effects within a webpage. It is an interpreted scripting language and its code is run in a web browser. It is also called a browser’s language and can be used for client-side developments as well as server-side developments. It was developed by Brendan Eich at Netscape and was first released in 1995.

Features of JavaScript: Some important features of JavaScript are:

It is a lightweight scripting language.
It is platform-independent, it can run anytime on any platform or any browser.
It can handle date and time easily as it has in-built functions for date and time.
It allows dynamic typing and defines types of the variable on the basis of stored value.
It provides support for Object-Oriented programming.
It reduces the load on the server by providing greater control to the browser itself.

Example:

javascript

console.log("Hello Geeks, Greetings from GeeksforGeeks")

JSP stands for Java Server Pages and is a dynamic web technology based on servlet container and Java EE specification which is used to generate dynamic web content on webpages.

Features of JSP: Some important features of JSP are :

It is an expression language for the server side.

html

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
