Скачать или смотреть Why Does This JavaScript Code Throw an Error? 🤔 Const Variables Explained!

In this video, we explore an interesting JavaScript behavior:
1️⃣ Declaring a constant variable (const) with the value 3 and trying to reassign it to 5 throws an error.
2️⃣ Declaring a constant array (const) with a value of [3], and updating its first element to 5 works without any issues.
3️⃣ Declaring a constant object (const) with a property a: 3, and updating the property value to 5 also works just fine.

Why does the first condition throw an error, but the other two work perfectly?
What's the difference between reassignment and mutation when it comes to const variables?
I show you the results of each scenario and leave the big question to you—why does this happen?
