find() iterates the iterator and invokes the callbackFn function once for each element. It returns the element immediately if the callback function returns a truthy value. Otherwise, it iterates until the end of the iterator and returns undefined.If find() returns an element, the underlying iterator is closed by calling its return() method.. The main .find 方法會對每個元素執行一次 callback 函式，直到找到一個讓 callback 函式回傳 true 的元素。 當元素被找到的時候，find 會立刻回傳該元素，否則 find 會回傳 undefined。 callback 會被使用於陣列索引自 0 至 length - 1，並會被用於每一個的陣列索引，而不僅是那些有賦值 .
