Use let here to allow re-assigning – var is a legacy keyword from ES5.

- Comment can be removed as it's already clear what the code is doing.
- Missing space after
if. - Theoretically there might be a method prefixed with
_having the same name, so usingwhilehere would be better.

Field- and method-names should follow the coding style, i.e. camelCase, not CamelCase.

- Let's move these 3 lines to right after the
let, as they belong together. Then put a blank line between that and thefieldHandlestuff (those two lines), and then one blank line before assigning tojsFields. Just to make the code a bit more readable. - Missing a space before
{.

Don't see any trailing whitespace :'( Do you mean the extra line ? Maybe that's because I'm on windows :/ cr/lf vs lf ? |

The last blank line isn't blank, it's got spaces before the CRLF. |

Allow interception when a field and a method have the same name.
note : I've added some unit tests that I wasn't able to run (no build env here)
Should fix #20 :)
