你好，这个 PR 是为了在素材集市发布扩展。请问审核进度如何？有需要我修改的地方吗？谢谢！ |
|
数学功能原版scratch和七星松的数据分析扩展中大部分能实现，字符串功能也是七星松的字符串处理有 |
|
数组功能七星松的变量数组扩展也有 |
|
而且强烈不推荐使用中文作为函数和i18n key，显得很“初学者” |
|
同时这是官方approved的扩展库，扩展集市的审核不需要在这里pr |

There was a problem hiding this comment.
没必要bind，1.你的func没有用this
2.gandi调用func时自己就有bind

为啥不直接发扩展集市呢，官方扩展库原则上不再添加了新扩展了
