typescript

object与any

https://blog.csdn.net/wq_static/article/details/50238291

class Blablabla {
   field: Object;  //Object
}

var my = function(bla: Blablabla){
    bla.field.comingMethod();  //错误, 属性comingMethod在Object不存在
}

//修改成any类型后
class Blablabla {
   field: any;  //any
}

var my = function(bla: Blablabla){
    bla.field.comingMethod();  //OK, 只有在运行时才会关心comingMethod方法是否真的存在.
}
//可以在运行时动态分配方法
var bla = new Blablabla();
bla.field = {
    comingMethod: function(){ console.log('hi any!'); }
    //lambda表达式写法: 
    //comingMethod: ()=> console.log('hi any!')
}

my(bla); // hi any!
