An example of an AI chatbot conversation about debugging hoisting issues in JavaScript.
How can I debug hoisting issues in JavaScript?
Hoisting in JavaScript can lead to unexpected behavior. Can you share a specific example you're facing?
Sure! I have a function that uses a variable before it's declared, and it's returning undefined.
That sounds like a classic hoisting issue. In JavaScript, function declarations are hoisted, but variable declarations are not. Can you show me the code?
Here's my code: console.log(x); var x = 5; Why does it log undefined?
In your code, the declaration of x is hoisted, but its assignment is not. So, console.log(x) runs before x is assigned, resulting in undefined. You can fix it by declaring x before using it.
