redeclare_constant.js

// Step 1: Define a function with a constant variable
let myFunction = function() {
    const myConstant = 42;
    console.log("The value of myConstant is:", myConstant);
};

// Step 2: Call the function to demonstrate it works
myFunction(); // Outputs: The value of myConstant is: 42

// Step 3: Delete the function by setting the variable to null
myFunction = null;

// Step 4: Trying to call the function now would result in an error
// myFunction(); // TypeError: myFunction is not a function

// Step 5: Redeclare the function
myFunction = function() {
    const myConstant = 42;
    console.log("The value of myConstant is:", myConstant);
};

// Step 6: Call the redeclared function to demonstrate it works again
myFunction(); // Outputs: The value of myConstant is: 42
