Скачать или смотреть Check If Value Is Array | Why typeof Fails?

In this quick JavaScript interview tutorial, we answer a common question:
“How do you correctly check if a value is an array in JavaScript?”

The typeof operator returns "object" for arrays, so it fails.
The correct method is: Array.isArray(value) — reliable, clean, and used in real-world JavaScript and React projects.

Perfect for beginners, freshers, and frontend interview preparation.
