Или тарикатската:)

function bombNumbers(numberArea, specialNumber) {
    while (numberArea.includes(specialNumber[0])) {
        let bombIndex = numberArea.indexOf(specialNumber[0]) - specialNumber[1];
        numberArea.splice(bombIndex < 0 ? 0 : bombIndex, specialNumber[1] * 2 + 1);
    }
    console.log(numberArea.reduce((a, b) => a + b, 0))
