Javascript "classes" (without frameworks)

Question

I am doing my first javascript project that uses objects heavily. Due to how this works, almost all user objects are executed as follows:

namespaceobj = {};
namespaceobj.subobject = {};
namespaceobj.subobject.somefunction = function(arg, uments) {
    // Do Stuff
}
namespaceobj.subobject.somedata = 10;
namespaceobj.othersubject = {};
namespaceobj.othersubject.somefunction = function(some, args) {
    // Do more stuff
}
// More subobjects etc.

This is normal, since all user objects have only one instance (examples of sub-objects are the user interface, tools, general data, etc.).

However, I saw that the code did something like this (the syntax is probably incorrect, it's just from memory, seeing similar code)

function SomeClass() {
    this.somedata = 42;
    this.somefunction = function(a, few, args) {
        // Do Stuff
    }
}
// More classes and stuff
// Elsewhere:
someInstance = new SomeClass(); // AFA I recall, new was optional
someInstance.somefunction();

Can someone explain how the “classes” in the second example work, and any errors that I may encounter when using them.

function SomeClass() {
    var somedata = 42;
    this.somefunction = function(a, few, args) {
    // Do Stuff like:-
    return somedata + a;
  }
}
// More classes and stuff
// Elsewhere:
someInstance = new SomeClass(); // AFA I recall, new was optional
someInstance.somefunction(15);  //returns 57
