Example usage

// Example usage.
import { RangeErrors } from '@angular-package/error';

// Define range errors.
const rangeErrors = new RangeErrors('(RE: 4332)', '(RE: 4331)', '(RE: 4330)');

// Set the `RangeError` objects under the given identification numbers.
rangeErrors
  .set(
    'Age is 99',
    'Age must be',
    '(RE: 4330)',
    9,
    27
  )
  .set('Height can not be 11000', 'Height', '(RE: 4331)', 1, 1000);

// Returns RangeError: Problem(RE: 4330): Age is 99 => Fix: Age must be must be between 9 and 27
// of type RangeError<"EG: 4330", undefined, undefined> | undefined.
rangeErrors.get('RE: 4330');
