This is one of the most educational and entertaining reads on the internet, if you are into that kind of thing:
Has anyone actually read through that? Reading the first few examples and it’s just not understanding how languages work half of the time:
!!"false" == !!"true"; // -> true !!"false" === !!"true"; // -> trueWow, no shit, non-empty string coerces to true, who would’ve guessed! Did you know that
!!"bullshit" === !!"true"as well? Mind=blown.NaN === NaN; // -> falseAgain, no shit, that’s in the NaN specification and the page even mentions it, so why even include it?
Which is why I’m of the opinion that dynamically typed languages are evil. !!“false” should either be caught at compile time or raise an exception.
I’m thoroughly convinced that the only use of dynamically typed languages is to introduce bugs
I am with you. To me these are non-obvious details, just a bug waiting to silently happen in production.
Why? IMO that’s perfectly valid. The various type coercions are sometimes crazy, but IMO the rule that non-empty string is coerced to
trueand empty string tofalseis very simple to follow. The snippet is not even a gotcha, I don’t see anything worth failing over. Putting “true” or “false” in a string doesn’t change that.
The tech equivalent of inventing leaded gasoline.
Just a reminder that JavaScript was developed in 10 days, the same amount of time i spend fixing bugs when i just miss a “,”
The world was made in 7 days, so it should have been 3 days left to develop js
This sounds more credible than the big bang theory. I no longer believe in science
Physics was written in JavaScript?
…checks out.
