JavaScript Intensive Tutorial - A Summary of Native.js Examples

This article is the official HTML5 training course of the H5EDU organization. It mainly introduces: JavaScript Intensive Course - Native.js Example Summary

Although Native.js is powerful and open, many web developers cannot complete it independently because they are not familiar with the native API.
The purpose of this post is to summarize various written NJS codes for the convenience of web developers.
Everyone gathers firewood and the flame is high, and capable developers submit NJS code a lot, and everyone will give you a thumbs up.
