/*

Part 1: Debugging Challenge
The JavaScript code below contains intentional bugs related to type conversion.
Please do the following:
  - Run the script to observe unexpected outputs.
  - Debug and fix the errors using explicit type conversion methods like  Number() ,  String() , or    Boolean()  where necessary.
  - Annotate the code with comments explaining why the fix works.

Part 2: Write Your Own Examples
Write their own code that demonstrates:
  - One example of implicit type conversion.
  - One example of explicit type conversion.

  *We encourage you to:
Include at least one edge case, like NaN, undefined, or null .
Use console.log() to clearly show the before-and-after type conversions.

let result = "5" - 2;
console.log("The result is: " + result);

// let isValid = Boolean("false"); // will return true since it is a non empty string
let isValid = false; // added direct assignment to variable
if (isValid) {
    console.log("This is valid!");
} else { // added an else statement to display if isValid is false
  console.log("This is not valid!");
}

let age = "25";
// let totalAge = age + 5; should be converted to number
let totalAge = Number(age) + 5; // converted age to a number with Explicit Type Conversion
console.log("Total Age: " + totalAge);

function myAge() {
} 
console.log(myAge());
// A function with no return statement will automatically return undefined
