You are debugging a JavaScript application and encounter a ReferenceError at runtime, despite a function being defined in the code. What could be the possible reason if the function was defined using a function expression?
- The function is declared within a block scope.
- The function was defined in strict mode.
- The function was hoisted to the top of the code.
- The function was defined inside another function.
When a function is defined using a function expression and declared within a block scope, it may not be accessible outside of that block, resulting in a ReferenceError. This is because the function's scope is limited to the block where it's defined.
