In this course, you will develop an intuitive understanding of the new features of jаvascript in ES6+: iterators, generators, promises, and async/await. You'll understand how promises are implemented under-the-hood to truly help fix the challenge of inversion of control in asynchronous code design. Plus, use iterators and generators to master asynchronous control flow. Go under the hood and solve complex async challenges by using the call stack, event loop, callback queue, micro-task queue and browser APIs so that you can navigate complex asynchronous problems, easily!
