Boilerplates

December 1, in preparation for day 2

l = document.body.textContent.trim().split(/\r?\n/) // owo
.map(Number)

December 2: I put the .trim() stuff on a new line so I could easily comment out document.body.textContent to put in an example input.

l = document.body.textContent
.trim().split(/\r?\n/) // owo v2
.map(Number)

December 13: I set up an anonymous function for Array#map since it seems the inputs aren’t just a list of numbers anymore. This way, I can also easily use it as a for loop if I’d like.

lines = document.body.textContent
.trim().split(/\r?\n/) // owo v3
.map(line => {
return +line
})

December 14: More and more of the days have chunks separated by two newlines, so I decided to group up \r?\n with a noncapturing group with a quantifier. I probably could just do with \n\n since Advent of Code uses LF, but whatever. I also put a semicolon before lines in case I wanted to do an array destructure, though in most cases I don’t have any lines before it so it’s usually not needed.

;lines = document.body.textContent
.trim().split(/(?:\r?\n){1}/) // owo v4
.map(line => {
return +line
})

December 21: I made the input page dark theme for my eyes’ convenience. I also set up the array destructure ahead of time, as well as added some indentation so it at least starts off looking tolerable.

document.documentElement.style.colorScheme = 'dark' // 🥰
;[...lines] = document.body.textContent
  .trim().split(/(?:\r?\n){1}/) // owo v5
  .map(line => {
    return +line
  })
