How does the temporal dead zone impact function expressions in JavaScript?
- It prevents the use of arrow functions in function expressions.
- It enforces a delay in the execution of function expressions.
- It causes a runtime error if a variable is accessed before its declaration in a function.
- It makes function expressions execute before other code in the same scope.
The temporal dead zone (TDZ) is a phase during the variable initialization in JavaScript. It occurs between the variable's declaration and its assignment. During this phase, trying to access the variable will result in a ReferenceError. This impacts function expressions as variables declared within them are also subject to the TDZ. If you try to access such a variable before its declaration, it will lead to a runtime error.
