3 special numbers

infinity,-infinity and NaN.

The minus operator can be both binary and unary operators.

> console.log(typeof 4.5)
number

> console.log("Zoro" < "Luffy")
false # more or less alphabetical

> console.log(NaN == NaN)
false # Not a number nosensical computation doesn't equal other NaN

Logical operators
