Nodejs WTF



  • Here's a bit of Friday entertainment for you all. I saw this on StackOverflow and thought I'd share for your amusement :-)

    TLDR: REPL insets implicit parentheses around each statement so the following:

    hi)(

    becomes:

    (hi)()

    and therefore compiles and runs!

    You can even pass arguments to a mangled function call like so:

    hi)(args

    and this becomes:

    (hi)(args)

    and compiles and runs correctly.

    I'll have to remember this one for the next bring your own code competition. :-) I think this feature has got a lot of potential for evil code and WTF-ery.

    Eric Lippert made me laugh in the comments with <quote>And I thought automatic semicolon insertion was bad.</quote>



  • Somebody at some point in their life, hopefully not on an LSD trip, thought this was a good idea? I don't want to live on this planet anymore.



  • Now if browsers were to support js completion/insertion for:

    () {} ;
    it would allow programmers to focus on the important parts (i.e. the beginning) and let the machine deal with the details. People spend way too much time checking for those closing symbols while they should think about Features.


    
    var p = $.post('/submit', function 
      confirmSubmit(
    .done(function( { $('#Message.text('Thank you 
    .fail(function(xhr, err 
        alert($(xhr.responseText   
    
    

    I think I will send that suggestion to the Firefox team. How hard can it be, browsers already do that for html tags!

    Make sure to tell them to update their credits list!

  • They should insert function. That would be the real time saver.

    And then why stop there? Make them insert return and for too. In the case of for, the declaration of the iteration variable should be optional too.

    As for while and if, I'm sure they can find a way of determining which was meant when a boolean expression is seen, also for when you omit the initialization and afterthought in a for loop.

    Keep up with that kind of silliness and you end up at CoffeeScript.

    They're probably already using Excel for it anyway.
