What are the differences between JavaScript and Ajax?

Answer 1

Javascript is a scripting language used to program various actions to be executed by the web browser. It can be used for more than just AJAX.

AJAX involves using Javascript and other client-side and server-side technologies to provide seamless user experience, such as some element of the page being updated without entire page being reloaded from the server.

AnswerAJAX is a part of Javascript programming. Javascript is just a client-side scripting language that is used to control a web page once a user has downloaded the page. AJAX is a particular usage of Javascript in which javascript communicates with the remote script and receives the response from the server, without having to reload the whole page. AnswerJavascript is a client-side scripting programming language... AJAX is a technique incorporating the use of Javascript, a server-side scripting language, and XML. But javascript is the main core of ajax-based systems. AJAX stands for Asynchronous Javascript and XML. AnswerAJAX :

Ajax is the acronym for Asynchronous JavaScript and XML. It incorporates a suite of technologies aimed at improving user experience with web pages. It also allows programs written in different programming languages on different browsers to communicate with each other. Translation, communication and function between web applications happens remotely and, ideally, instantaneously. Another primary aim of Ajax is to reduce user delay when interacting with web pages. Ajax frameworks and technological components allow web applications to function on an as-need basis without requiring the re-loading of the entire web page.

JavaScript:

Javascript, on the other hand, is a client side scripting language that allows the creation of dynamic web pages providing a new level of interactivity. The advantage of JavaScript is that since it's a client side application, it can create dynamic web pages that are more complex than what a server side script can do. Server side scripts are run by the host machine and thus, has very limited resources especially when there are a lot of people accessing that server. Being on the client computer, Javascript has a lot of resources to play regardless of the activity on the server.

The prime drawback of Javascript is that it is a very good candidate for a Trojan to be installed into your computer. Because it runs on the client, it is authorized some resources that could potentially give control of your computer to an outsider, potentially getting you included in a botnet. The remedy to this drawback is by not allowing untrusted javascript codes from being run on your computer.
