The birth of JS

28 comments

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

The tech equivalent of inventing leaded gasoline.

This is one of the most educational and entertaining reads on the internet, if you are into that kind of thing:
https://github.com/denysdovhan/wtfjs
- Has anyone actually read through that? Reading the first few examples and it's just not understanding how languages work half of the time:
  undefined
  
  !!"false" == !!"true"; // -> true !!"false" === !!"true"; // -> true
  Wow, no shit, non-empty string coerces to true, who would've guessed! Did you know that !!"bullshit" === !!"true" as well? Mind=blown.
  undefined
  
  NaN === NaN; // -> false
  Again, 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
  
  NaN===NaN is the fault of the floating point standard tho i believe.
  
  Also, a huge proportion of the list is just not understanding IEEE floats behaviour and blaming the language for it. Exactly like this post is doing. All those weird number things js does is because it only uses floats for everything and every language that uses floats will behave the exact same way.
- So, uh, first example, the developer decided instead of comparing based on type, he rather converts the values? Why?!

Ah. The shork did the math. This explains a lot.

You just have to look at the problem from a different angle.

Not enough alcohol involved.

What is this image from?

  She is their most subscribed talent and is known for being computationally challenged.
  
  Thanks!

Approach the problem from different angle!
