I need to check for falsy or empty array props in an object, and I do not know how to make it so it checks all nested props. Any guidance?

I've done this for now but it won't work if the prop has a nested object with more props

export const objectPropsNotEmpty = (obj: Record<PropertyKey, unknown>) => {
  for (const prop of Object.values(obj)) {
    if (prop instanceof Array) {
      if (!prop.length) {
        return false;
      }

      continue;
    }

    if (isNil(prop)) {
      return false;
    }
  }

  return true;
};

export const objectPropsNotEmpty = (obj: Record<PropertyKey, unknown>) => {
  for (const prop of Object.values(obj)) {
    if (prop instanceof Array) {
      if (!prop.length) {
        return false;
      }

      continue;
    }

    if (isNil(prop)) {
      return false;
    }
  }

  return true;
};

recursion?

export const objectPropsNotEmpty = (obj: Record<PropertyKey, unknown>) => {
  for (const prop of Object.values(obj)) {
    if (typeof prop === 'object' && prop !== null) {
      if (!objectPropsNotEmpty(prop)) {
        return false;
      }
    }

    if (prop instanceof Array) {
      if (!prop.length) {
        return false;
      }

      continue;
    }

    if (isNil(prop)) {
      return false;
    }
  }

  return true;
};

export const objectPropsNotEmpty = (obj: Record<PropertyKey, unknown>) => {
  for (const prop of Object.values(obj)) {
    if (typeof prop === 'object' && prop !== null) {
      if (!objectPropsNotEmpty(prop)) {
        return false;
      }
    }

    if (prop instanceof Array) {
      if (!prop.length) {
        return false;
      }

      continue;
    }

    if (isNil(prop)) {
      return false;
    }
  }

  return true;
};
