## Throw function

Throws a value written in the problems pane, similar to the throw syntax. 
```
 pxt.throwValue(null);
```

The difference is that the function is the core of the syntax in the MakeCode environment.

Here is the shim for getting the function.

`//% shim=pxt::throwValue` 

Comments from the MakeCode Team.
``` ts
// this is equivalent to JS `throw v`; it will leave
// the current function(s), all the way until the nearest try block and
// ignore all destructors (think longjmp())
```
