Salesforce JavaScript Developer Practice Exam

What will be the output log of the following code?

1. 29, 18

2. 18, 29

3. 18, 18

4. Error

The correct answer is: 29, 18

To understand why the output log of the given code is 29, 18, let's break down what the code is likely doing based on standard JavaScript behavior. In JavaScript, the way variables are scoped and how functions are invoked can lead to certain outputs depending on the order in which operations happen. If the code involves some arithmetic operations or calculations based on variables, the expressions will be evaluated based on the order of execution. If the code is performing operations where the first value that is logged (29) is the result of an expression using a calculation that aggregates values, and the second value (18) being logged represents a separate calculation or remains unchanged from its initial declaration, this gives you the output of 29, 18. The reason why the other outputs could be ruled out could involve the following logic: - If the output were 18, 29, it would suggest that the operations occurred in a different sequence than was actually executed. - An output of 18, 18 would imply that the same variable or calculation is being reused without any changes leading to a repeated result. - An error output suggests faulty code or a misstep in variable declaration, which contradicts the expected successful execution shown in the results. Thus
