Bug in the JavaScript

A musical parody of Billy Joel's 'Piano Man', about JavaScript.

[@EriAirlangga]

Singing about JavaScript but this song was written in C

[@christhomasson4972]

lol!

[@whatstheairspeedvelocityof7618]

And it's also sung in C.

[@christhomasson4972]

Cast into an abyss?

[@DeepHouseX]

That's genius!

[@arwahsapi]

Should've tuned it up to C#

[@kongchan437]

Billy would be so proud of you

[@piros100]

"'cause everything else was built properly but the front end's a pile of crap" 🤣🤣🤣 I relate to that on a deep, spiritual level.

[@julianapelnar518]

It's Friday night, I have a drink in my hand, the code in front of my eyes... And the bug in the JavaScript. This is all so amusingly true it made me cry while laughing.

[@tomaszswirski3161]

Empty array casts to true so there is a bug in that song too

[@aj.arunkumar]

"and your objects are hashes, but when your code crashes you'll find they were functions as well" man that was deep 😅

[@luskira]

hahahahhahahahaha

[@TremereTT]

I think the real problem is the speed JS changes... I learned it from the free PDF EleoquentJS.pdf and it's a bit older ... and today allmost nothing in there is usefull anymore. JS regularly throws whole principles over board. Making a JS App automantically comes with giant amounts of maintenance of the code... It's disgusting.

[@Silverflame1]

I thought that functions are objects in JavaScript (function objects) instead of the other way around.

[@Gurmudgin]

Bug fixing, the bane of my existence, and all summed up in one song. Great job.

[@ericduminil]

Can someone please explain "at the end of 1969"? I suppose it has something to do with `new Date(0)` being at the end of 1969 in US timezones, but I couldn't manage to get a falsy value out of it.

[@tvonwieseseen2774]

Maybe it's because `new Date(false)` is legal and returns epoch 🙂. It also rhimes nicely, fits the metrum and (to me) alludes to eternity (HGTTG) /and/ the 60s. I♥how F12 gives anyone instant access to JS's power and delicate beauty. ♥

[@traveller23e]

If you try to get the boolean value of a date, it will basically do a cast to int and then to bool. Hence the Unix epoch being the only value that is false (all other dates parse to true).

[@ericduminil]

​@@traveller23ethanks. What would be the corresponding js code?

[@traveller23e]

@@ericduminil I'm not a js dev these days, but googling some and playing around here's the fuller explanation: Normally time comparisons are done by calling the .getTime() function, because otherwise js just compares the objects (almost always returning false). However if you use getTime() (including implicitely via a conversion that calls valueOf) it becomes a number, specifically 0 for the Unix epoch which will evaluate to false. Here's some code that demonstrates it: var postEpochDate = new Date(1975, 6, 23, 12, 30, 0, 0); var postEpochDateClone = new Date(1975, 6, 23, 12, 30, 0, 0); var preEpochDate = new Date(1965, 6, 23, 12, 30, 0, 0); var epochDateProbablyWrongTimezone = new Date(1970, 0, 0, 0, 0, 0, 0); var epochDate = new Date(0); var testDates = [preEpochDate, epochDateProbablyWrongTimezone, epochDate, postEpochDate]; console.log(postEpochDate == postEpochDateClone); console.log(postEpochDate.getTime() == postEpochDateClone.getTime()); for(let i = 0; i < testDates.length; i++){ console.log(testDates[i].toUTCString()); if(testDates[i].getTime()){ console.log("The above date evaluates to true."); } else{ console.log("FALSE!!!"); } }

[@SmilingJ]

Yes I have problems reproducing this myself. I think it's kind of funny and I wish I had a snippet to back that claim. But all my attempts failed so far 😢

[@ChronologicalLogic]

honestly, this is a brilliant rendition of the original song, and with the know how of javascript (full stack front ender oriented here) this touches some personal notes hehe

[@NN-kf7qo]
