在本文中，我们将讨论 NodeJs、AJAX 和 JQuery 之间的区别。首先，让我们讨论一下 JavaScript，JavaScript 是技术领域增长最快的编程语言之一。因为它是一种非常灵活的编程语言，具有一些非常有用的优势，例如托管、动态原型设计等。由于其一些重要的框架和库，所有这一切都成为可能。

NodeJs ： NodeJs 是 JavaScript 的运行环境，工作在 v8 引擎上，非常强大，所以 nodeJs 利用这一点，让 JavaScript 在 nodeJs 的帮助下作为服务器端语言运行。
阿贾克斯： AJAX 代表异步 javascript 和 XML，用户向服务器请求数据，无需任何重新加载和阻塞，任何其他请求也因此提供了将数据获取到服务器并显示到页面的流畅性能。
查询： 这个 javascript 库使一切变得简单，并提供了一种非常有效的方法来在前端做某事，并提供许多基本功能，如浏览器事件处理、DOM 动画、Ajax 交互和跨浏览器 JavaScript 开发。
Nodejs、AJAX 和 jQuery 的区别：
| NodeJs | AJAX | JQuery |
|---|---|---|
| NodeJs is an open-source framework based on JavaScript v8 engine. | AJAX is a web development technique for making asynchronous calls to the server. | jQuery is a JavaScript library for designing and make some web development tasks easy. |
| It makes it possible to run javascript outside of the browser. | It works on the browser or outside the browser also. | It makes it easy to use AJAX in your project. |
| It works with one non-blocking i/o modal. | It works with one non-blocking asynchronous request. | Block other events if the current event is running. |
| It only works with JavaScript. Because it is the runtime environment for JavaScript. | It works with various technologies. | It also works with different technologies. |
| It is written in C, C++, JavaScript, and CoffeeScript | This is written in JavaScript. | This is also written in JavaScript. |
| They support dependency injection in terms of packages. | It does not support any dependency injection. | It support but is very limited to front-end dependency injection. |
| It works on the server-side. | It only works on the client-side. | It also works on the client-side. |
| For creating a server machine or serving static or dynamic files around the Internet. | Fetching data from API endpoints. | Works only to build the rich front-end user interface. |
