no-render-return-value.md

Disallow usage of the return value of Inferno.render (inferno/no-render-return-value)

💼 This rule is enabled in the ☑️ recommended config.

Inferno.render() (inferno-compat) currently returns a reference to the root InfernoComponent instance. However, using this return value is legacy and should be avoided because future versions of Inferno may render components asynchronously in some cases. If you need a reference to the root InfernoComponent instance, the preferred solution is to attach a callback ref or createRef() to the root element.
