I am facing a strange problem in JavasSript.
There are three variables (declared as var), they all store an object; say var object1, object2 and object3.
Ok, so what I do now is I assign object2=object1 and object3=object1.
And when I add something to object2, it automatically gets added to object3. Strange? 😐
Please help. I think I am missing some basic funda here, but I am not able to catch it.
So how is that strange?
You pass reference to the object and do not clone the object. So any modification of your variables object1 to object3 actually refer to the same object, thus “automatically updating all variables”.
