React Native/Javascript - How to know that object does not have the property?

Let say
:

myVariable.color;
myVariable.height;
myVariable.width;

But
sometimes, myVariable only have "color" and "height"
property.

I have try this, but no luck
:

if(myVariable.width ==
            undefined) {
//but not filtered
            here
}

How
to know if myVariable doesn't contain "width" property by code, is it possible
?
