How can i constrain func params?

[YouCii]

onCheckChange={(isChecked) => this.props.onCheckChange(isChecked)}

SettingItem.propTypes = {
    onCheckChange: PropTypes.func
};

It's not enough to constrain the 'onCheckChange' without parms-limit. Maybe I express my needs clearly.

There's not really a way to do it with JS (without layering a type system on top).

Since propTypes are run on the prop value - which doesn't provide any information about what arguments it's going to eventually be called with - it's basically impossible to check this with propTypes.

emmming, a little pity. Thanks for your reply @ljharb
