ABOUT THIS COURSE

Kirupa is an MIT grad who works at Microsoft as Senior Program Manager. He has been tinkering with web technologies since 1998. He works on the Edge browser team where he gets to sink his teeth into the cutting-edge web technologies. HTML5 is taking over the browsers and one of the coolest things in HTML5 is the canvas - the immediate mode drawing surface you have in HTML for bringing pixels to life using JavaScript. It is used to create games, graphs, and animations. This is an extensive course with interactive playgrounds (so you don't have to install anything). The course can be divided into four parts. 1. Understand basics of Canvas and compare it with DOM. 2. Learn how to draw shapes. 3. Take a deep dive into canvas transformations and animations. 4. Explore advanced mouse and keyboard handling to create truly interactive applications using canvas. If none of what I just wrote makes sense, then the content here is just what you need 😀 . Let's get started.

These are high-quality courses. Trust me the price is worth it for the content quality. Educative came at the right time in my career. I'm understanding topics better than with any book or online video tutorial I've done. Truly made for developers. Thanks

Just finished my first full #ML course: Machine learning for Software Engineers from Educative, Inc. ... Highly recommend!

You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it.

Your courses are simply awesome, the depth they go into and the breadth of coverage is so good that I don't have to refer to 10 different websites looking for interview topics and content.
