Conclusion: Javascript is Neutral Evil

That is a valid point. Also, I learned something about JavaScript. Thank you!

Well, it's something like the difference between { x: null } and { }.

I feel like it belongs more in the chaotic row

X is ten, as the Romans do

Let x be any number. => x is a number. QED.

boo

numbers aren’t real dipshits, they’re just letters that want to be special

A vector is a thing that can be added together and scaled in "the intuitive way." That is, for example, if a and b are numbers and v is a vector, then av + bv = (a+b)v (vector addition distributes over scalar multiplication). The prototypical example is the collection of arrows rooted at the origin on the 2D plane, where addition has a simple geometric interpretation (you put the tail of one vector at the tip of another, the resulting point is the new tip) and scaling is "stretching." But it really could be anything that adds and scales.

Not really.
