Replace a switch statement with multiple assignments to object literal

Question

I have a switch statement that I'd like to replace with an object literal but because multiple assignments are made for each case, I don't know how to do it.

switch (roll1) {
    case 21:
        rain = 1.25;
        break;
    case 22:
        rain = 1.5;
        solid = "light";
        break;
    case 23:
        rain = 1.75;
        solid = "light";
        break;
    case 24:
        rain = 2;
        solid = "light";
        break;
    case 25:
        rain = 2.25;
        solid = "medium";
        break;
    case 26:
        rain = 2.5;
        solid = "medium";
        hook = 1;
        break;
    case 27:
        rain = 2.75;
        solid = "medium";
        hook = 5;
        break;
    case 28:
        rain = 3;
        solid = "heavy";
        hook = 10;
        break;
    case 29:
        rain = 3.25;
        solid = "heavy";
        hook = 15;
        break;
    case 30:
        rain = 3.5;
        solid = "heavy";
        hook = 20;
}
return [rain,solid,hook];

Note: solid & hook are given default values before the switch statement. I was looking at this example:

const dogSwitch = (breed) => ({
  "border": "Border Collies are good boys and girls.",
  "border2": "Border Collies are good boys and girls.",
  "pitbull": "Pit Bulls are good boys and girls.",
  "german": "German Shepherds are good boys and girls."
})[breed]
console.log(dogSwitch("border2"))

But each line of the object literal only assigns one value, not multiple. Please advise.

You can define object like below and then use Object destructuring to retrieve values for specified variables:

let doc = { 23: { rain: 1.25 }, 22: { rain: 1.5, solid: "light" }, 29: { rain: 3.25, solid: "heavy", hook: 20 } };

let {rain, solid, hook} = doc[29];

console.log(solid);
console.log(rain);
console.log(hook);
