JavaScript is a particularly flexible language. In the early years, it was considered a toy-like language that could only do a small job of painting web pages. The project project is not very large, let alone the application of design patterns in Javascript. However, with the rise of Nodejs, HTML5 and web2.0, JavaScript itself has become more and more important. Many classic programming ideas such as design patterns have also been applied to JavaScript to complete larger projects. We have collected "JavaScript Design Patterns Video Tutorial", hoping to help everyone better understand the concept of design patterns.
