NEW QUESTION # 32

// faster code statement here
}
Which statement meets the requirements to log an error when the Boolean statement evaluates to false?
Answer: C
Explanation:
console.assert(condition, message?) logs an assertion error if condition is falsy.
To log an error when number + 2 === 0 is false, use:
console.assert(number + 2 === 0);
Other options are invalid or do not behave as described: console.error always logs, assert alone is not a built-in browser global, and console.classy doesn't exist.

Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge Definitions:
False negative โ The test reports a failure even though the feature actually works.
False positive โ The test reports success when it should not.
True positive โ Correctly identifies something is working.
True negative โ Correctly identifies something is not working.
In this scenario:
The checkout button does exist, so the feature works.
The test fails incorrectly, because it is checking for the wrong selector.
That is the definition of a false negative.
