Likewise, flow through object properties and global variables is not modeled. Type inference The library semmle.javascript.dataflow.TypeInference implements a simple type inference for JavaScript based on intraprocedural, heap-insensitive flow analysis. Basically, the inference algorithm approximates the ...

The idea is that we can have a number of people through whom we can navigate, each with a name, age and a favorite color. As we use the previous and next buttons, we navigate to other people in the list, and if we press the button in the middle—the clock—we celebrate a birthday...
The for/in loop (described in Chapter 6) is also useful for debugging. You can use it, along with the alert() method, to display a list of the names and values of all properties of an object, for example. This kind of function can be handy when exploring the language or trying to...
