Flow 0.46 Arity Flag #1223
Description
Flow has shipped a strict_call_arity flag, which will become the only option as of 0.47.
With this flag enabled, there are issues using the Map constructor, at a minimum (I haven't tried the other data types).
MCVE:
- using
flow-binv0.46 and thestrict_call_arityflag set - using Immutable 3.8.1
/* @flow */
import { Map } from 'immutable';
const myMap = new Map({ testKey: 'test value' });resulting in the following error:
testfile.js:26
26: const myMap = new Map({ testKey: 'test value' });
^^^^^^^^^^^^^^^^^^^^^^^^^ unused function argument
