JS: Highlighting of supposed classes and/or functions?

[RunDevelopment]

When reading JS code, you sometimes come across a line like this:

Foo.prototype.foobar = function() { ... };
Bar.constructor.apply();
foo.bind(this);
bar.apply(...);

We then use our common knowledge of JS and assume that Foo is a class because its prototype field was used to add the function foobar . Similar for Bar, foo and bar.

Generally: Can't we assume that the word left from prototype or constructor is a class and that the word to the right of prototype or the left of either apply, bind or call is a function?

Of course, this will cause false positives, but it will only do so on very few occasions.
