• try...catch (mdn)
• error object (mdn)
• typeof operator (mdn)

Explanation:

Step1: Add try block

try {

Step2: Call processNumbers

processedValue = processNumbers(numberElements);

Step3: Add catch block

} catch (error) {
    processedValue = -1;
}

Answer:

let numberElements = [1, 2, 5, 7]; // Code will be tested with different arrays.
let processedValue = 0;
try {
    processedValue = processNumbers(numberElements);
} catch (error) {
    processedValue = -1;
}
