Core module of the mass framework in the backend

The front and back ends of the mass framework are built based on node. js. Different from the front-end, the backend depends on Some APIs provided by the node. js built-in module. Therefore, the front-end dom api modules dependent on the browser cannot be reused. Currently, the core module only has Lang, which can be used by flow, and more, such as random, Pinyin, base64, and UUID...

Node. js has a built-in module loading mechanism, which is very inconsistent with the apis I use on the front end. I will package it again. The core module and the front-end core module should be consistent in other methods. Of course, domready does not need to be removed from the backend. For example, because the V8 engine supports ecma262v5, the data type can be simplified. The biggest difference is that debug uses mass. log, and its second parameter indicates formatting and highlighting.

CodeIt is temporarily here, and various extensions will be made in the future!
