What are some examples of temporal dead zones in different programming languages?

Temporal dead zones occur when a variable is accessed before it is declared. In JavaScript, for instance, using let or const creates a temporal dead zone from the start of the block until the variable is declared.

Can you give me more examples from other languages?

Sure! In Python, accessing a variable before its assignment in a function will raise a NameError. Similarly, in Swift, using a variable before it's initialized leads to a compile-time error.

Are there any languages where this doesn't happen?

Yes, in languages like C or C++, variables declared at the beginning of a block are accessible throughout the block, so they don't have a temporal dead zone.

How can I avoid temporal dead zones in my code?

To avoid temporal dead zones, always declare your variables at the top of their scope or use them only after they have been initialized.
