Beautiful! findIndex() is super powerful.
💛 JavaScript tip 💛
indexOf uses strict equality comparison under the hood.
This means it can only ever find the exact reference but not an identical object.
'findIndex' fixes this because you can pass a callback you can use to identify an object. ↓
![// won't work const array = [
{ prop: 1 },
{ prop: 2 }
];
const indexOfObject = array.indexOf({ prop: 1 });
// => -1 !
// this will work
const array = [
{ prop: 1 },
{ prop: 2 }
];
const indexOfObject = array.findIndex((element) => element.prop === 1);
// => 0 !](/pic/orig/media%2FFRvU837WYAE9DK-.jpg)
ALT // won't work const array = [ { prop: 1 }, { prop: 2 } ]; const indexOfObject = array.indexOf({ prop: 1 }); // => -1 ! // this will work const array = [ { prop: 1 }, { prop: 2 } ]; const indexOfObject = array.findIndex((element) => element.prop === 1); // => 0 !

Just curious, are you using => functions exclusively or still sticking to traditional function syntax?
No judgement!

A spicy take that is also…hydrating? Who knew it could be done! 🌶️
Curious to hear the JS community's take on this!
"DRY" is an acronym introduced, seemingly universally, to software engineers early in their education.
