    (I've just noticed that How is capitalised, after the comma on the previous line, and now I'm more triggered by that.)

  2. Array Holes Are NOT undefined?!

    MIND BLOWN! An empty slot in an array is NOT the same as undefined. The hole doesn't exist as a property! map() SKIPS holes but processes undefined. This invisible difference will break your code!

  7. void Operator ERASES Any Value?!

    The void operator is JavaScript's BLACK HOLE! It takes ANY expression and returns undefined. Even when the function returns 42, void turns it into NOTHING! This ancient operator will confuse everyone!

  8. Oh boi! Looks like on the August my schedule is big :dragnaww:

    1) Speech about #Emacs in SaintP #hackspace (0x08.in/)

    2) Speech about #Xserver (configurarion and hidden gems) in the same hackspace

    3) Speech about my heavily modified #Thinkpad X220 in SaintP area (Roschino town) in #Undefined #hacker festival (undefined.chaosconstructions.r). It will be streamed in the Internet and if I'll be able to obtain a resulting video — I'll upload it to my PeerTube.

  9. If you've ever wanted a crash course in #programming #roulette 🎰, look no further than this guide to #undefined #behavior in #C and #C++. Apparently, the best way to learn is to cross your fingers and hope your program doesn't implode 💥. Who needs safety nets when you have the thrill of silent, lurking errors? 🙈
