🔍 GUESS THE OUTPUT #1 - full breakdown

We apologize for marking wrong answe as correct in previous question. Explanation was correct, but right answer was not marked properly by accident.

Correct answer is false.

Here are some additional ones.

javascript
console.log(0.1 + 0.2 === 0.3);
console.log([1, 2, 3] + [4, 5, 6]);
console.log(typeof NaN);

Answers:
1️⃣ false - floating point math isn't exact. 0.1 + 0.2 = 0.30000000000000004
2️⃣ "1,2,34,5,6" - arrays get coerced to strings and concatenated, not added
3️⃣ "number" - yes, NaN is technically a number type. Ironic, we know.
