es6, the key value of an object can only be a string. Whether you assign it or get it, it will convert your key to a string before operating
.var a = {};
a[a] = 1;
//{[object Object]: 1}es6.
it is not appropriate for you to give an example here, because result will treat 000 as '0' , that is, the reason why your result [000] result is undefined is not because there is no '000' key, but because there is no ' 0' this key
var a = {};
a[000] = 1; //{0: 1} 
Oh, it is indeed a string, but the console displays like a number ~
