About this course

WHY I WROTE THIS COURSE

After teaching React extensively (33.000+ students), be it online for a larger audience or on-site for companies transitioning to web development and React, I always come to the conclusion that React is all about JavaScript. Most of it boils down to JavaScript ES6 and beyond features and syntax, but also ternary operators, shorthand versions in the language, the 'this' object, JavaScript built-in functions (map, reduce, filter) or more general concepts such as composability, reusability, immutability or higher-order functions. While you don’t need necessarily to master all of these before starting with React, they will come up while practicing it and so to learn them will put you at a great advantage. This course is my attempt to give you comprehensive JavaScript skills that will make your React journey smooth and straight-forward.

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

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.
