Trying to figure out what string.length and print(var) exist in a single language.... Not Java, not C# (I'm pretty sure its .Length, not length), certainly not C, C++ or Python, Pascal, Schme or Haskell or Javascript or PHP.

JavaScript has [string].length

doesnt have print nor allow variable declaration without keywords

print() will print the text to a physical printer with paper and everything. Don't confuse it with console.log and use it in a loop.

it's so rough learning this by accident

It would have print if it was previously declared as function.

Also, js is as dirty as you want it to be. Keywords are indeed not necessary for declaring variables.

JavaScript is the language of the assassins, with its infinitely modifiable prototypical setup

Nothing is true

true !== 1

true

true + true + true === 3

true

Everything is permitted

[]+[]

''

Sure you can write foo = 3 in JavaScript. It’s a global variable and can be referenced as either foo or window.foo.
