how to observe if variable changes value in javascript?

Question

I know of Object.observe() and Object.prototype.watch() but those are not very widely suported features (unfortunatly), meanwhile I know AngularJS does something to watch changes on objects...

I'm trying to create an script with this capability but much much lighter than Angular. First I remembered that I saw somewhere in this site that object properties could have (or had) set and get methods. That sounded strange to me maybe my memory is weak.

Am I in the right direction? Any enlightment on how to do this?

What do you want to watch? An object?
