This is an experimental inter-procedural analysis that detects impure functions. It is meant to be an improvement over the [purity](/docs/next/checker-purity) analysis with a negation on the issue types. For each function, impurity analysis keeps track of not only the impurity of the function but also some additional information such as which parameters/globals the function modifies.

This analysis checks that all non-optional [`@Prop`](https://fblitho.com/docs/props)`s have been specified when constructing Litho components. This is a [Litho](https://fblitho.com/) specific checker.
This checker detects opportunities to hoist function calls that are invariant to outside of loop bodies. The hoisting analysis relies on [purity](/docs/next/checker-purity) analysis to determine whather a function is pure or not.
This is an experimental inter-procedural analysis that detects pure (side-effect free) functions. For each function, purity analysis keeps track of not only the purity of the function but also some additional information such as whether the function modifies a global variable or which of the parameters are modified. It models functions with no summary/model as modifying the global state (hence impure).
