Conditional Return Type

~~I have a question. Let's say, I want to create a function that takes in 1 optional parameter arg of type T. The function also returns the value of the optional parameter.~~

function foo<T>(arg?: T) {
  return arg
}

function foo<T>(arg?: T) {
  return arg
}

~~In this scenario, is it possible for me to affect the return type to where it would return the value as T or as T | undefined based on whether or not arg is provided?~~

const test1 = foo<string>() //typeof test1 === string | undefined
const test2 = foo('string') //typeof test2 === string

const test1 = foo<string>() //typeof test1 === string | undefined
const test2 = foo('string') //typeof test2 === string

LOL forgot about function overloading... Nevermind.

Abstract Class

Getting an error saying

src/server/components/Holdable.ts:26:21 - error TS2345: Argument of type 'typeof Holdable' is not assignable to parameter of type 'Constructor<object>'.
  Cannot assign an abstract constructor type to a non-abstract constructor type.

src/server/components/Holdable.ts:26:21 - error TS2345: Argument of type 'typeof Holdable' is not assignable to parameter of type 'Constructor<object>'.
  Cannot assign an abstract constructor type to a non-abstract constructor type.

I'm new to abstraction so I'm not sure if the way I've set it up is causing this problem but I'm having trouble debugging. Looking for someone to help me understand this error and how I might fix it.

import { OnStart } from "@flamework/core";
import { Component, BaseComponent } from "@flamework/components";

interface Attributes {}

export interface HoldableInstance extends Model {
    PrimaryPart: (Part | BasePart) & {
        PromptAttachment: Attachment & {
            ProximityPrompt: ProximityPrompt;
        }
    }
}

@Component()
/**
 * Abstract class for holdable items
 */
export abstract class Holdable extends BaseComponent<Attributes, HoldableInstance> implements OnStart {
  abstract debugTag: string

  onStart() {
    print(this.debugTag);
  }
}

import { OnStart } from "@flamework/core";
import { Component, BaseComponent } from "@flamework/components";

interface Attributes {}

export interface HoldableInstance extends Model {
    PrimaryPart: (Part | BasePart) & {
        PromptAttachment: Attachment & {
            ProximityPrompt: ProximityPrompt;
        }
    }
}

this.destroy() unexpected behavior?

It says "Destroys this component instance." but after calling it I don't see that it was destroyed.

open() {
    this.minInteractions = 0;

    const egg = this.instance;
    const top = egg.Top;
    const bottom = egg.Bottom;
    
    top.Base.WeldConstraint.Destroy();
    top.Parent = game.Workspace;
    bottom.Base.WeldConstraint.Destroy();
    bottom.Parent = game.Workspace;
    
    this.destroy();
}

open() {
    this.minInteractions = 0;

    const egg = this.instance;
    const top = egg.Top;
    const bottom = egg.Bottom;
    
    top.Base.WeldConstraint.Destroy();
    top.Parent = game.Workspace;
    bottom.Base.WeldConstraint.Destroy();
    bottom.Parent = game.Workspace;
    
    this.destroy();
}

setInterval without destroying it to update state?

I have a perdicament where I want to update state on an interval. Every way that I go about it I find myself being forced to use the dependency array of the useEffect for the setInterval so I can get updated state values. This causes my interval to just be destroyed and rebuilt every interval because of state changing on the interval. How can I achieve this interval without ever having to destroy it to listen to state changes?

  const [incrementCount, setIncrementCount] = useState(1);
  const [translationX, setTranslationX] = useState([...INIT_TRANSLATION_X]);

  const incrementTranslationX = useCallback(() => {
    if (incrementCount && incrementCount % 2 === 0) { //* the condition
      setIncrementCount(0);
      setTranslationX([...INIT_TRANSLATION_X]);
    } else {
      setIncrementCount((prev) => prev + 1);
      setTranslationX((prev) => [prev[0] + INCREMENT, prev[1] + INCREMENT]);
    }
  }, [incrementCount, translationX]);

  //loop interval
  useEffect(() => {
    const interval = setInterval(() => {
      incrementTranslationX();
    }, INTERVAL);

    return () => {
      clearInterval(interval);
      console.log("DESTROYED INTERVAL");
    };
  }, [incrementTranslationX]); //! cannot update (the condition) without this

  const [incrementCount, setIncrementCount] = useState(1);
  const [translationX, setTranslationX] = useState([...INIT_TRANSLATION_X]);

  const incrementTranslationX = useCallback(() => {
    if (incrementCount && incrementCount % 2 === 0) { //* the condition
      setIncrementCount(0);
      setTranslationX([...INIT_TRANSLATION_X]);
    } else {
      setIncrementCount((prev) => prev + 1);
      setTranslationX((prev) => [prev[0] + INCREMENT, prev[1] + INCREMENT]);
    }
  }, [incrementCount, translationX]);

  //loop interval
  useEffect(() => {
    const interval = setInterval(() => {
      incrementTranslationX();
    }, INTERVAL);

    return () => {
      clearInterval(interval);
      console.log("DESTROYED INTERVAL");
    };
  }, [incrementTranslationX]); //! cannot update (the condition) without this

Dynamic index signature parameter type

How can I create a dynamic index signature parameter type that doesn't require all of the keys from the mapped type?

enum Color {
  cyan = 'cyan',
  white = 'white',
  gray = 'gray',
}

type Variants = {
  [style: string]: {[key in Color]: string}
}

const foo: Variants = {
  solid: {
    gray: '...'
  }
}
//error: Type '{ gray: string; }' is missing the following properties from type '{ cyan: string; white: string; gray: string; }': cyan, white

enum Color {
  cyan = 'cyan',
  white = 'white',
  gray = 'gray',

type Variants = {

}

const foo: Variants = {
  solid: {
    gray: '...'
  }
}
//error: Type '{ gray: string; }' is missing the following properties from type '{ cyan: string; white: string; gray: string; }': cyan, white

Unexpected Behavior

I am trying to assign players to slots in my state, this is what my state looks like

//this.lanes
{
  team1: {
    slot1: {
      stat1: number
      stat2: number
      player?: Player
    },
    slot2: {
      etc...
    }
    etc...
  }
  team2: {
    etc...
  }
}

//this.lanes
{
  team1: {
    slot1: {
      stat1: number
      stat2: number
      player?: Player
    },
    slot2: {
      etc...
    }
    etc...
  }
  team2: {
    etc...
  }
}

When I iterate over the players (in my test case only 1), the same player is assigned to EVERY slot.

setupPlayers() {
    const players = shuffle(PlayerService.GetPlayers())
    players.forEach((player, index) => {
      this.assignPlayerToTeam(player, index)
    })
  }

setupPlayers() {
    const players = shuffle(PlayerService.GetPlayers())
    players.forEach((player, index) => {
      this.assignPlayerToTeam(player, index)
    })
  }

assignPlayerToTeam(player: Player, index: number) {
    let side: keyof typeof this.lanes = "team1"
    if (index <= 3) side = 'team2'
    if (index === 0) this.lanes[side].slot1.player = player
    else if (index === 1) this.lanes[side].slot2.player = player
    else if (index === 2) this.lanes[side].slot3.player = player
    else if (index === 3) this.lanes[side].slot4.player = player
  }

assignPlayerToTeam(player: Player, index: number) {
    let side: keyof typeof this.lanes = "team1"
    if (index <= 3) side = 'team2'
    if (index === 0) this.lanes[side].slot1.player = player
    else if (index === 1) this.lanes[side].slot2.player = player
    else if (index === 2) this.lanes[side].slot3.player = player
    else if (index === 3) this.lanes[side].slot4.player = player
  }
