Tricky JavaScript Interview Questions | #0085 #javascript

Welcome to Coding Frontier,
In this example:

javascript
Copy code
value = 10;
When we run this code, it throws a ReferenceError because the variable value is not declared.

Why?
Hoisting only applies to declared variables, not undeclared ones. Since value wasn’t declared, the JavaScript engine doesn’t recognize it during execution.

Fix:
Add var to declare value:

javascript
Copy code
var value;
value = 10;
Now, it works because value is hoisted and initialized to undefined. Always declare variables to avoid such errors!
