Thank you for your attention and good evening: D

store#get() returns the value of its key, if it exists, otherwise that value will be undefined . Then you can use it to check if something is set for a particular key:
if(store.get('chave')){
// Existe.
}
I've created an example in jsfiddle because the snippets here in StackOverflow do not allow the use of storage :
