What is the difference between accessors and normal functions in javascript object?

Question

What is the specific difference between these two functions (one is an accessor property getter) in a javascript object other than the manner in which they are called?

var o = {
  foo: function() { return "bar"; },
  get foo2() { return "bar2"; }
}

Answer 1

From MDN, Sometimes it is desirable to allow access to a property that returns a dynamically computed value, or you may want to reflect the status of an internal variable without requiring the use of explicit method calls. In JavaScript, this can be accomplished with the use of a getter.

A method is a function associated with an object, or, simply put, a method is a property of an object that is a function. Methods are defined the way normal functions are defined, except that they have to be assigned as the property of an object.

foo2 acts more like a property than a method which will/can hold a dynamic value.

var o = {
  foo: function() {
    return "bar";
  },
  get foo2() {
    return "bar2";
  }
};
//To invoke 'foo'
console.log(o.foo());
//To invoke 'foo2'
console.log(o.foo2);
