Course Overview

Modern JavaScript From The Beginning 2.0 (Just Updated)

A 40-hour master course to take you from beginner to advanced JavaScript

This is a 40+ hour in-depth course that will take you from the absolute beginning of JavaScript, learning about data types, functions and loops to learning DOM manipulation, asynchronous JS with promises, async/await and much more. You will even learn how to write unit tests for algorithms. We go into how JavaScript works under the hood including execution context, the call stack, event loop, etc. We learn about Webpack tooling and how to create a modern development environment. At the end, we build a Node.js/Express API with a custom Webpack frontend.


All of the code in the learning modules will go into a folder called "JavaScript Sandbox". This is so we can keep things organized and you can always refer back to it for any code snippets that you may need. All of the final and starter code for the projects is included as well as links to the GitHub Repos.


WHAT YOU WILL LEARN


  • Basics & Fundamentals: Data types, let & const variables, functions, conditionals, loops, object literals, etc

  • Data Structures - Arrays, objects, maps, sets as well as custom data structures like stacks and queues

  • DOM Manipulation - Selectors, traversing the DOM, show/hide, creating & removing elements, event listeners

  • OOP - Constructor functions, prototypes, inheritance, classes, protected properties, getters/setters

  • Async JS - Ajax & XHR, Fetch API, callbacks, promises, async / await

  • Error Handling - Try...Catch, HTTP errors

  • Web & Browser APIs - Canvas, geolocation, audio/video, web animations API

  • Modules & Tooling - CommonJS & ES Modules, Webpack,  plugins, loaders, modern dev environment &  workflow

  • Unit Testing Algorithms - Learn the Jest testing library and algorithms like palindromes and anagrams

  • Node.js & Express - Learn about Node modules, NPM packages and build a REST API with Express & MongoDB

  • Full Stack Development - We build an API with Express and a frontend with Webpack. No frontend frameworks!

  • So So Much More!

    The core JS is really good, as he goes through all the important things, has some exercises, examples projects etc. The negative part is that in many occasions, he will spend many hours to methods that are not in use anymore. Maybe because the course is very old, but JS OOP, old API methods and many more, are not any good to a beginner. I have spend many hours, to end up realising that the newer methods are not only easier, but way more relevant.

    Brad seems like he knows the subject matter, but he's a terrible teacher. .No quizzes, very few challenges so almost no chance to use what's taught in the lessons. The instructor dives into advanced concepts almost immediate without letting the student get comfortable with the basics. Take functions for example; he introduces them and then almost immediately goes into arrow functions, using "const myFunction" instead of "function myFunction", hoisting, etc etc and we've barely had any practice writing ANY functions. Really frustrating. I've typed out and followed along with most of the "projects" but I'm lost and nothing is sticking. Course is frustrating and at this point I'm not sure I could write any javascript beyond 'console.log("hello world")' - and I've put HOURS into this course.

    What was great: 1) I loved that the course had multiple different projects. 2) All tools worked that were used in the course. 3) I have 3 years of JS experience and were still able to find many interesting solutions or some new cool features I didn't know about before. What could be improved: PACE was super quick, but then again, my playback speed was 1.5.
