The Jaesque Style

this is javascript

Fantastical bits

• Put each statement on its own line(s)
• Don't add ; at the end of your statements
• If your statement is impure; mark it with a ; in the front!
  • Why? Javascript expressions always play well with Automatic Semi-colon Insertion. It is the prefixes in statements which potentially cause problems (e.g. hello () \n [] .forEach (...) on the next line is confused with hello () [] .forEach, which gives errors like Unexpected token ]). So we can safely escape statements, and only statements! And the only statements that are not 'impure' are variable assignments, which also respect Automatic Semi-colon Insertion.
  • e.g. No console .log (x). It's impure, so ;console .log (x)
• If your function is impure; make it {;}!
  • e.g. No x => console .log (x). It's impure, so x => {;console .log (x)}
• Don't use this, use require ('thiss')
• No function statements
• Make your functions generic. Use x, y, z, t, u, v, w, q, r, s, ... for the parameters (Unless they are really specific, obviously unreusable)
  • What is this? basically the 'ABC' song triplets/quadruplets/quintuplets
• Add spaces between tokens
• Avoid suffixes smaller than the prefix. It is undiscoverable.
  • e.g. This is bad. The significant call operator () is undiscoverable! Is this a function or the value?

var result = (x => {
   ...
   var computation = step_1 + step_2
   return result
}) ()

• Mark your sentence with the one significant prefix (if its in a phrase), hide the rest on the previous line. Encourage the leading member to follow the [ or (
  • e.g. (the prefix here is o)

var result = Oo (something,
  o (x => x .parent),
  o (R .reduce ((sum, x) => sum + x, 0)))

or

var q = [ document .querySelector ('fire')
  , document .querySelector ('earth')
  , document .querySelector ('air')
  , document .querySelector ('water') ]

• Collapse the )s, }s, etc.

Aesthetic bits

• Use tabs
• Use single quotes ''
• Use snake_case (since hyphen-case does not work)
• Do add a space before .. The property is a word!
  • e.g. document .body .style .backgroundImage = 'url(doge.png)'
• Use arrow functions, and only arrow functions!
• Arrow functions with one parameter, take no brackets
• Curry!
• Use var, and var only
• Try to not mutate vars
• No class statements
• Write your unfinished code as ...
