Bug 142890 – Web Inspector: Adopt ES6 Class Syntax for all Controller Objects

• Component: Web Inspector
• Status: RESOLVED FIXED

[Matt Baker]

* SUMMARY
Adopt ES6 Class Syntax for all Controller Objects.

* NOTES
The const keyword isn't allowed in strict mode, and ES6 class method scope uses strict mode implicitly. Instances of const will need to be replaced with var.

This will throw a ReferenceError since it'll access "this" before calling super()

Must fix those super calls.

Yes, this is replacing:

    WebInspector.Annotator.call(this, sourceCodeTextEditor);

So the "this" is not needed. This should just be:

    super(sourceCodeTextEditor);

You can test this at runtime by using the Type Profiler.

Same.

Weird that some of our WebInspector.CodeMirrorFoo classes extend WebInspector.Object and others don't. Maybe they all should.

Trailing whitespace!

> +    get()

Very interesting. I wonder if we should avoid this change. For now, I'd prefer this to be "get: function()" as thinking about it at a high level, this is a get property that is a function, not a method. I think it makes more sense to use the old syntax here.
