What Is The Difference Between Javascript's Object Literals And Object That Appears To Be Named When Console Logged?

I have noticed there are times when I console.log an object, I get the object literal and sometimes its seems what is console.logged is prefixed with a name. For example, If I con

Solution 1:

The latter is an instance of a named class:

classResource{
   constructor() {
      this.id = ...;
      this.date = ...;
   }
}

Or a named constructor:

function Resource() {
  this.id = ...;
  this.date = ...;
}

In both cases, the class or constructor in instantiated with the new keyword, but class is the newer ES6 syntax.

console.log(newResource())

Your first example is simply a plain object with no constructor.

Solution 2:

They have a constructor property, that does not point to Object, but to Ressource in that case.

Solution 3:

The console is giving you hints, it doesn't always log stuff as is.

For example:

varCat = function (name) {
    this.name = name;
}

var paws = newCat('paws');
console.log(paws);

will act similar to Resource in your example. The console is hinting at the constructor.
