assert: support arrow functions in .throws() #3276

LGTM. Two weeks back I faced the same problem and tried the exact same fix locally :D |
|
Isn't it enough to do |
|
@targos Wouldn't it be better if we let v8 take care of it? |

What @thefourtheye said. I'm inclined to be reactive here, not proactive. An explicit check like that can be subverted. |

Nit: there are two white spaces between both sentences.

You may have noticed that I do that in most places. It's called double spacing and religious wars have been fought over whether or not it's a good thing.

Double spacing is spacing between lines... I think you guys are referring to the spaces after the period, in the comment? (maybe not; then please ignore this comment)

OK then LGTM |
`x instanceof f` where f is an arrow function throws a (spec-conforming) "Function has non-object prototype 'undefined' in instanceof check" exception. Add a workaround so that it's possible to pass arrow functions as the second argument to assert.throws(). The try/catch block is a little jarring but swapping around the clauses in the if statements changes the semantics too much.

@bnoordhuis ... should this land in v4.x before LTS is cut? |
|
Good point. Yes, tag added. |
