The difference between Var a=new Object () and Var a={} in JavaScript

Both are generated as a default object object.

JS and other languages, all objects are the base class is object, so the new object () and simple {} is the same empty object, is the default object.

Originally I thought {} should be an object without any properties and methods, but it turns out that:

var a = {},a.tostring () object objects have methods that have a.

This can also be judged, in fact a = {} is a = new Objcet () simple implementation. Just like in the Java language, string str = "" and string str = new string () are all objects that create a string.
