Determining the availability of props.visible

[devdammit]

Hello Guys! I noticed that you check the props.visible by the presence of it in props. Why not check for undefined?

https://github.com/react-component/tooltip/blob/b5e43fd3128f6bec414c7bb0308a4f998105118a/src/Tooltip.jsx#L72

We use a rule eslint - react/require-default-props. And set props.visible as undefined in the defaultProps. And if the props.visible is equal to undefined, then he still gets to extraProps.popupVisible.

But why, are you going to lint code in node_modules.

@benjycui, No, of course, we do not check node_modules into the style code. :) We have our UIkit, and we made a wrapper for rcTooltip. In this wrapper we describe props

Why not check for undefined?

Yep, you can PR.

But I don't agree with this ESLint rule, we can set default prop for defaultXXX, but I don't think we should set default props for controlled props(e.g. value, visible..)

@benjycui I agree with @mochachai, need to check it for undefined. For example in my case I need to use rc-tooltip in two different scenes inside the one component.

1. Will work like a standard tooltip
2. Will show preview with always opened tooltip

So I was going to just pass true or undefined in 'visible' props, but now I have to do one trick:

const props = {};
if (preview) {
  props.visible = true;
}

return (
  <Tooltip placement="bottom" {...props} />
)
