Function groupVals

Takes an object of key-value pairs containing ReadonlyVal instances and their corresponding ValSetValue functions, and returns a tuple containing an array of the ReadonlyVal instances and a function to set their values.

Example

const [vals, setVals] = groupVals({
 a: readonlyVal(1),
 b: readonlyVal(2),
 c: readonlyVal(3),
});

vals.a.value; // 1

setVals.a(2);
Copy

This is useful for classes that have multiple ReadonlyVal instances as properties.

export interface Foo$ {
  a: ReadonlyVal<number>;
  b: ReadonlyVal<number>;
  c: ReadonlyVal<number>;
}

export class Foo {
 public $: Foo$;
 private setVals: { [K in keyof Foo$]: ValSetValue<UnwrapVal<Foo$[K]>> };

 public constructor() {
  const [vals, setVals] = groupVals({
    a: readonlyVal(1),
    b: readonlyVal(2),
    c: readonlyVal(3),
  });

  this.$ = vals;
  this.setVals = setVals;
}
