▲ [WARNING] The "??" operator here will always return the left operand [suspicious-nullish-coalescing]

    src/app/app.component.ts:28:25:

  The left operand of the "??" operator here will never be null or undefined, so it will always be returned. This usually indicates a bug in your code:

    src/app/app.component.ts:28:12:
      28 │     field = !!(vlue.hue) ?? false;
