JavaScript Asynchronous Operations and CRUD APIs in Node.js

⭕ Overview In this video lecture, we'll learn some fundamental concepts and examples of how asynchronous operations work in JavaScript. We'll start by learning features of JS functions and how callback functions are created and utilized. Then we'll explore Promises, AJAX (XMLHttpRequest), and te fetch API. Finally, we'll learn to create simple API's for CRUD operations using Node.js and Express.js. ⭕ Chapters 00:00:00 Introduction 00:04:22 Intro to callback functions in JS 00:05:58 JS functions are first-class citizens 00:16:18 JS functions are high-order 00:23:00 Asynchronous example in JS 00:30:01 Promises 00:46:50 AJAX (XMLHttpRequest) 00:55:20 The fetch API 01:01:55 Creating custom APIs using Express.js 01:07:00 Creating the GET APIs 01:21:03 Creating the POST API 01:23:44 Creating the PUT API 01:27:07 Creating the DELETE APIs ⭕ About me I am a Web instructor and author for Linkedin Learning (formerly Lynda.com), Packt, E-C Council, Udemy, and MC Press. ⭕ Visit my site: https://christianhur.com ⭕ My complete online training courses: ☑️ REST APIs & AJAX Operations Using Node, Express, and jQuery: https://www.udemy.com/course/rest-apis-ajax-operations-using-node-express-and-jquery/?referralCode=A762AE70D9FD6A931F9B ☑️ Build Clean and Secure PHP Web Apps From Scratch: https://www.udemy.com/course/build-clean-and-secure-php-web-apps-from-scratch/?referralCode=C200BB52F0C7153B93CC ☑️ Angular 9 New Features: https://www.packtpub.com/web-development/angular-9-new-features-video ☑️ Full-Stack Web Development with Flask: https://www.packtpub.com/web-development/full-stack-web-development-flask-video ☑️ Full-Stack Web Development with Django & Angular 8: https://www.packtpub.com/web-development/full-stack-web-development-with-django-and-angular-8-video ☑️ Angular 7 New Features: https://www.packtpub.com/web-development/angular-7-new-features-video ☑️ The DOM in JavaScript, jQuery, AngularJS, and React : https://www.linkedin.com/learning/the-dom-in-javascript-jquery-angularjs-and-react ☑️ Building JSF Web Applications with Java EE 7: https://www.linkedin.com/learning/building-jsf-web-applications-with-java-ee-7 ☑️ Troubleshooting Vue.js: https://www.packtpub.com/application-development/troubleshooting-vuejs-video ⭕ Check out my book: Developing Business Applications for the Web: With HTML, CSS, JSP, PHP, ASP.NET, and JavaScript is available on Amazon and MC Press. ☑️ Link: https://www.mc-store.com/collections/christian-hur/products/developing-business-applications-for-the-web-with-html-css-jsp-php-asp-net-and-javascript
