var my_object = Object.create({}, {
getBar: {
value: function() {
return this.bar;
}
}
});
my_object.bar = 1;
alert(my_object.getBar());
What is the reason for getBar being the function and not value?
var my_object = Object.create({}, {
getBar: {
value: function() {
return this.bar;
}
}
});

Given the usage of Object.create requiring property descriptors as input :
propertiesObjectWhen specified and not set to
undefined, it is an object containing enumerable own properties that define property descriptors for additions to the newly-created object, along with corresponding property names.
The definition of value:
value
The value associated with the property. (applies only to data descriptors). Defaults toundefined.
The need for using getFoo suggests opting for an accessor property:
let my_obj = Object.create({}, {
foo: {
get: function(){
return this._foo; },
set: function(newValue){
this._foo = newValue;
}
}
});
It seems that the issue arises from assigning a function to a variable.
If you intend to execute the function anonymously, remember to include parentheses after the declaration like this:
x = { y : function(){return 2;}}
x.y
function (){return 2;}
x = {y : function(){return 2;}()}
x.y
2
Make sure to add () at the end of the function declaration as shown above.
Apologies for the concise explanation; I just copied it directly from a JavaScript console.
