Description:

If you can answer these questions, you don’t need this presentation: If everything is an object, why does “2.toString()” throw an error? What is the value of function(a,b,c){ return a+b+c; }.length? What is the scoping level for JS variables? How can you implement private members in a JS object? How can you implement inheritance in JS? Is it possible to enforce a specific context on a JS function?

These questions will be answered, and many more! Delivered with a loving dose of real-world use.
