+Passing a new search term directly to the `searchHeroes()` after every user keystroke creates excessive HTTP requests, which taxes server resources and burns through data plans.
 
 Instead, the `ngOnInit()` method pipes the `searchTerms` observable through a sequence of RxJS operators that reduce the number of calls to the `searchHeroes()`. Ultimately, this returns an observable of timely hero search results where each one is a `Hero[]`.
