Example of using dynamic function call via map + reduce for adding boolean values

FormValidationHelper.js

const validate = (value, allValues, meta, validationTypes) => {
  const ret = validationTypes.reduce((sum, next) => {
    console.debug({ sum, next });
    return sum && next(value, allValues, meta);
  }, true);
  console.debug('V_A_L_I_D_AT_I_O_N_', ret);
  return ret;
};

const required = value => {
  return value ? undefined : 'validation.required';
};

const test = (value, allValues, meta) => {
  console.debug({ value, allValues, meta });
  return true;
};
const test2 = (value, allValues, meta) => {
  console.debug({ value, allValues, meta });
  return false;
};

export const VALIDATION_TYPE = {
  REQUIRED: required,
  TEST: test,
  TEST2: test2
};

export default validate;
