What is the temporal dead zone in programming?
An example of an AI chatbot conversation about the temporal dead zone in programming.
What is the temporal dead zone?
The temporal dead zone (TDZ) refers to the period in JavaScript where a variable is in a 'dead zone' and cannot be accessed.
Why does the temporal dead zone occur?
It occurs due to the way JavaScript handles variable declarations with let and const. They are hoisted but not initialized.
Can you give me an example of the temporal dead zone?
Sure! If you try to access a variable declared with let before its declaration, you'll get a ReferenceError.
How can I avoid issues with the temporal dead zone?
To avoid issues, always declare your variables at the top of their scope before using them.
