CoffeeScript 的指导原则是:"她仅仅是 JavaScript". 代码一一对应地编译到 JS, 不会在编译过程中进行解释. 已有的 JavaScript 类库可以无缝地和 CoffeeScript 搭配使用, 反之亦然. 编译后的代码是可读的, 且经过美化, 能在所有 JavaScript 环境中运行, 并且应该和对应手写的 JavaScript 一样快或者更快. ...
Defined incocos/core/event/eventify.ts:126 toString •toString:string 返回对象的字符串表示形式。 Asset对象将会重写Object对象的toString()方法。 当资源要表示为文本值时或在字符串连接时引用时, JavaScript 会自动调用 toString() 方法。 对于原始类型的资源,它将返回this.nativeUrl。
