Q7

scores = [
    {
        'ranking': 7.4,
        'name': 'Liza',
    },
    {
        'ranking': 3.2,
        'name': 'Bob',
    },
    {
        'ranking': 7.8,
        'name': 'Oscar',
    },
]
const sortAscending = (items, prop) => items.sort((a,b) => (a[prop] > b[prop]) ? 1 : ((b[prop] > a[prop]) ? -1 : 0))
const calculateAvg = (items, prop) => items.reduce((a, b) => a + b[prop], 0) / items.length;

console.log(sortAscending(scores,'ranking'))
console.log(calculateAvg(scores, 'ranking'))
