Thread of Helix refactor examples in practical situations

[nikitarevenco]

I think it's beneficial to have a thread where we can share how the helix motions can be used in practical applications to refactor code. Feel free to share yours here, if I have any cool ones in mind I'll also add a comment.

I'll start

Converting the following object into an array of tuples, each tuple's first element is the color name and the second is the color value

const palette = {
  white: "#ffffff",
  lilac: "#dbbfef",
  lavender: "#a4a0e8",
  comet: "#5a5977",
  bossanova: "#452859",
  midnight: "#3b224c",
  revolver: "#281733",

  silver: "#cccccc",
  sirocco: "#697C81",
  mint: "#9ff28f",
  almond: "#eccdba",
  chamois: "#E8DCA0",
  honey: "#efba5d",

  apricot: "#f47868",
  lightning: "#ffcd1c",
  delta: "#6F44F0",
};

1. Go inside the object and run mr{[ to replace surrounding curly braces with square brackets
2. mi[ to select everything within the array
3. s to enter select mode
4. :<enter> to place a cursor on every : character
5. r, to replace every : with a , (comma)
6. t,; to move cursor on each line to the ending comma, the semicolon collapses all selections to a single cursor
7. vgs to make a selection on each line from the beginning (excluding whitespace) up until, but excluding the comma
8. ms[ to surround with square brackets (array)
9. l to move 1 character forward
10. e to select until the end of each word
11. ms" to surround the items with double quotes to make strings

Complete command: mr{[mi[s:<enter>r,t,;vgsms[lems"

Output:

const palette = [
  ["white", "#ffffff"],
  ["lilac", "#dbbfef"],
  ["lavender", "#a4a0e8"],
  ["comet", "#5a5977"],
  ["bossanova", "#452859"],
  ["midnight", "#3b224c"],
  ["revolver", "#281733"],

  ["silver", "#cccccc"],
  ["sirocco", "#697C81"],
  ["mint", "#9ff28f"],
  ["almond", "#eccdba"],
  ["chamois", "#E8DCA0"],
  ["honey", "#efba5d"],

  ["apricot", "#f47868"],
  ["lightning", "#ffcd1c"],
  ["delta", "#6F44F0"],
];
