Javascript能做的事情越发的多了起来，随之而来的问题即是Js代码量的增加，面对代码的加多，我选择了仿面向对像类实例化里的构造函数自动启动的方式，把所有的js代码，以注册的形式，类化了起来。

P70系列延期，华为新旗舰将在下月发布
3月20日消息，近期博主@数码闲聊站 透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。
而博主@定焦数码 爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？
根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
