I am working on Frontend React and Javascript. I need to know, if there is a way to get the memory used by a javascript variable mostly for objects and non primitive values. I checked chrome dev tool, but couldn't find any option to get memory being used by a variable or constant.

Is there a way I can stop people from seeing the Javascript Source code that includes the Server API key and server information?

Is there any way to see the native code of javascript build-in functions in browser console so I can Know the algorithm efficiency of the function and how it actually works

I need to internationalise the javascript messages in the frontend, I'm using play framework 2.2.1, for backend messages I followed this: http://www.playframework.com/documentation/2.0.x/ScalaI18N

Play has no native support for JS internationalization, anyway you can easily do it yourself using common JS files containing objects with labels + small method for finding proper translation.
Check this answer - you'll find there full implementation for Play 2.x
