ES6 Find the maximum number of an array of objects

Question

I have the following data

shots = [
    {id: 1, amount: 2},
    {id: 2, amount: 4}
]

Now I\'m trying to get the object which

Answer 1

There are two problems here, the first is that a reduce needs a return value. the second is you're comparing a number with an object.

Therefore, I think you need something like this:

// This will return the object with the highest amount.
let highest = shots.reduce((max, shot) => {
    return shot.amount >= max.amount ? shot : max;
}, {
    // The assumption here is that no amount is lower than a Double-precision float can go.
    amount: Number.MIN_SAFE_INTEGER
});

// So, we can convert the object to the amount like so:
highest = highest.amount;

Edit:

A clean short one liner would look something like so:

const highest = shots.sort((a, b) => b.amount - a.amount)[0]
