In JavaScript, why is my globally declared variable not accepted by the loop in my function?

edit

There could be several reasons why a globally declared variable is not accepted by a loop in a function:

1. Scope issue: If the variable is declared outside of the function, the loop may not be able to access it if it is not within the same scope.

2. Timing issue: If the loop is executed before the variable is declared, the loop will not have access to the variable.

3. Name conflict: If the variable has the same name as another variable declared inside the function, the loop may be referencing the wrong variable.

To resolve the issue, make sure the variable is declared in the same scope as the loop and ensure that it is declared before the loop is executed. Also, double-check that the variable name is unique and not conflicting with other variables in the function.
