+// Part 1: Debugging Type Conversion
 
-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.
+// Convert "5" to a number and subtract 2
+let result = Number("5") - 2;  
+console.log("The result is: " + result); // Result is 3
 
-Part 2: Write Your Own Examples
-Write their own code that demonstrates:
-  - One example of implicit type conversion.
-  - One example of explicit type conversion.
+// "false" is a non-empty string, so it's always true
+let isValid = Boolean("false"); 
+if (isValid) {
+    console.log("This is valid!"); // This is valid!
+}
 
-  *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.
+// Convert "25" to a number before adding 5
+let age = "25";
+let totalAge = Number(age) + 5;
+console.log("Total Age: " + totalAge); // Total Age: 30

+// Part 2: Type Conversion Examples
 
-let result = "5" - 2;
-console.log("The result is: " + result);
+// Implicit conversion: "5" becomes a string, so we get "5" + "10"
+let number = 10;
+let resultImplicit = "5" + number;
+console.log("Implicit Conversion: " + resultImplicit); // 510
 
-let isValid = Boolean("false");
-if (isValid) {
-    console.log("This is valid!");

+// Explicit conversion: Convert "100" from string to number
+let strNumber = "100";
+let convertedNumber = Number(strNumber);  
+console.log("Before: " + strNumber); // Before: 100
+console.log("After: " + convertedNumber); // After: 100
 
-let age = "25";
-let totalAge = age + 5;
-console.log("Total Age: " + totalAge);
+// Edge case: "hello" can't be converted to a number, so we get NaN
+let invalidNumber = "hello";
+let invalidConversion = Number(invalidNumber); 
+console.log("Edge Case (NaN): " + invalidConversion); // NaN
