javascript - Using void(0) when function doesn't return anything -


why isn't practice put void(0) when function doesn't return explicitly?

function somefunc(a) {   // stuffs   return void(0); }

this when debugging stuffs.

thanks.

since void(0) resolves undefined, question "why isn't idea return undefined function?". using void(0) alternative undefined bad idea, relatively speaking, because it's more complex undefined, , less explicit. our goal programmers make simple, readable code others read , make sense of.

it's bad idea explicitly return undefined function same reason, introduces unnecessary complexity. typeof undefined evaluates undefined. makes writing tests more difficult , gives less insight purpose of function does, say, returning false.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
