 ### loadParser
 
 Loads and caches the parser by fetching `tree-sitter.wasm` and `tree-sitter-haskell.wasm`.
-This function is called internally by `parse` but calling it yourself might make the parser be ready faster, depending on your application.
+Make sure to call and await this function before calling `parse` or `evaluate`.
 
 ```js
-hs2js.loadParser().then(() => console.log('parser loaded'))
+hs2js.loadParser().then(() => hs2js.evaluate('alert "ready"'))
