Thid dumps is certainly valid. Pass yesterday with 88%. Nearly 90% questions are in this brain dumps. but there are several questions with wrong answers. You can care about these and study hard.

No.# A is correct

No.# 10 - 10 is the correct answer.

Here’s what happens step by step:

1. a is assigned the value 10.
2. b is assigned the value of a, which is 10.
3. changeValue(b); is called, passing the value of b, which is 10, to the changeValue function.
4. Inside changeValue, param is assigned the value 3, but this does not affect the value of b outside the function.
5. const result = a + ' - ' + b; assigns the string '10 - 10' to result.
6. console.log(result) prints '10 - 10'.

So, the final output will be:

10 - 10
