warning

Callable

• warning(condition: boolean, message?: null | string): void

---

• Assert that condition is truthy, else print a message using console.warn

  In production environment, message parameter could be stripped from source in order to reduce file size

  @example

  warning(true, 'this should be true');// pass
  warning(false, 'this should be true');// console.warn('Warning: this should be true')
