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. ↓
Another powerful use of findIndex(): const a = [2, 8, 73 /*,…*/]; const s = 55; if (1 + findIndex(x=>x==s)) { console.log("a contains s"); };
