Aggregate Elements [JavaScript]

let aggregateElements = (array) => {
    let numbersArray = array.map(Number);

    let sum = numbersArray.reduce((a, b) => a + b);
    let inverseValuesSum = numbersArray.reduce((a, b) => a + 1 / b, 0);
    let stringConcat = numbersArray.join('');

    console.log(sum);
    console.log(inverseValuesSum);
    console.log(stringConcat);
