As really old books says: For example an Apple is an Object. It has some features like color:green, camefrom:tree and so on and so on.

In Javascript actually almost everything i an object. Even HTML Elements are objects.

Example:

<div id="myDiv">My Text</div>
<script>
var myDiv=document.getElementById('myDiv');
console.log(myDiv);
console.log(myDiv.innerHTML);
console.log(myDiv.id);
</script>

Try it and see what your browser console says.

But of course you also may create an Object.

<script>
var myObj={fruit:'Apple',color:'green',gravitation:function(){var o=this; console.log(this.fruit+' color is '+this.color+' falls from the tree');}}
for(var i in myObj){
console.log(i+' = '+myObj[i]);
}
myObj.gravitation():
</script>

Try it and see what your browser console says. Play along those values.
