More expressions and less statements with arrows

You better do rather than declare!

Functional programming is all about what you “do” rather than what you “are” or what something “is,” and that’s a cool way to code. Statements, like a = a+b is the same as declaring with “is/are,” not what they do. So, in functional programming, the way could and should be a => a+b, and by that, you got one less state: there is no state a. You got an as an input, a + b as an output and that is it. You don’t need a state, or a “name” for your output as a, you just need the output a+b. In other words, you need one function with one expression for your output.
