Web front-end Promise tutorial from entry to mastery

This set of video tutorials is easy to understand and easy to understand. It dismantles the complex implementation step by step and uses a breakthrough design to explain step by step, making learning more interesting. The course content covers the practice of front-end and back-end asynchronous programming tasks, allowing you to understand Promise at a macro level. Five major parts of the course: 1. Introduction and basic use 2.Promise API 3. Several key issues in Promise 4. Customized packaging 5.async and await (the ultimate solution to asynchronous programming)
