 ## Checking for a cache hit
 
-You can check if the result of a momoized function resulted from a cache hit using the `cacheHit` getter on the `Memoizer` instance. Initially, if no memoized function has been executed, `cacheHit` is `undefined`; if the result of a memozed function was read from a cache file, `cacheHit` is `true`; if the result was just written to a cache file, `cacheHit` is `true`; if an exceptions occured, `cacheHit` is `undefined`.
