 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.
+Original Code and Unexpected Behavior
 
-  *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.
+javascript
+let result = "5" - 2;
+console.log("The result is: " + result); // Outputs: 3

+let isValid = Boolean("false");
+if (isValid) {
+    console.log("This is valid!"); // Outputs: This is valid! (unexpected)
+}
 
+let age = "25";
+let totalAge = age + 5;
+console.log("Total Age: " + totalAge); // Outputs: Total Age: 255 (unexpected)

-let isValid = Boolean("false");
+Fixed Code with Comments
+
+javascript
+// "5" - 2 works because JavaScript implicitly converts "5" to a number.
+// No fix needed here.
+let result = Number("5") - 2;
+console.log("The result is: " + result); // Outputs: 3
+
+// Boolean("false") returns true because any non-empty string is truthy.
+// To fix this, we need to check the actual string value.
+let isValid = ("false" === "true"); // Explicit comparison instead of Boolean conversion
 if (isValid) {
     console.log("This is valid!");
+} else {
+    console.log("This is NOT valid!"); // Correct output
 }
 
+// "25" + 5 results in string concatenation: "255"
+// Fix by converting "25" to a number first
 let age = "25";
-let totalAge = age + 5;
-console.log("Total Age: " + totalAge);
+let totalAge = Number(age) + 5;
+console.log("Total Age: " + totalAge); // Outputs: 30

+Implicit Type Conversion
+
+javascript
+let value = "10" * 2; // "10" is implicitly converted to number
+console.log("Implicit conversion result:", value); // Outputs: 20
+
+let input = undefined;
+console.log("Before conversion:", input, "Type:", typeof input);
+
+let converted = String(input); // Converts undefined to "undefined"
+console.log("After conversion:", converted, "Type:", typeof converted); // Outputs: "undefined", string
