Component library for React that uses observable state management and theme-able components.

import { values } from './values';

describe('values', () => {
  test('should return an array of values from an object', () => {
    const obj = {
      a: 1,
      b: 2,
      c: 3
    };

    const result = values(obj);

    expect(result).toEqual([1, 2, 3]);
  });

  test('should return an empty array if the object has no values', () => {
    const obj = {};

    const result = values(obj);

    expect(result).toEqual([]);
  });

  test('should throw a TypeError if the input is not an object', () => {
    const input = 123;

      // eslint-disable-next-line @typescript-eslint/ban-ts-comment
      //@ts-ignore
      values(input);
    }).toThrow(TypeError);
