My Solution

function format1(inputString) {
    // String slicing approach
    return inputString.slice(0, 4) + 'Y' +
        inputString.slice(4, 6) + 'M' +
        inputString.slice(6, 8) + 'D ' +
        inputString.slice(8, 10) + ':' +
        inputString.slice(10, 12) + ':' +
        inputString.slice(12, 14);
