 ## Caching
 
 `NFLData.jl` relies on Julia's JIT compilation to speed up running large objects into memory. However, JIT compiliation does not persist across sessions. `NFLData.jl` uses `Scratch.jl` to cache the data objects referenced across sessions, so subsequent calls that reference the same data objects are faster even if the call comes from a different Julia session. To learn more about this behavior, please visit the [Caching](caching.md) chapter of this docomentation.
