Answer 1

you can't inside the eval method. the code you give it is no code but a string. after the eval() then it becomes code and you can inspect it. This also depends on what tools you use to debug your script. In Chrome if you click Pause on exception, and execute your eval. it will break (because b is undefined) and jump in the evaluated code where you can step over, in and out. you can also use new Function("code goes here")() to evaluate code
