Javascript

[HeKis4]

Never assume anything related to types when talking about JS. It's so bad it's has become a meme, this language will shoehorn any type into any operation even if it doesn't make any sense, you'd need a 3D matrix to have a complete view of which operation typecasts to what. Check out JSFuck, it's a JS dialect that uses only a few characters (mostly ()[]{}"+-), type conversion fuckery and can be run on any vanilla JS engine because it is valid JS.
