VistasWhat is the best way to group and then sort an array of strings by their value?
I have an array of strings like this, however I'm not sure of how to group them, and then sort them. Inititially I used this function group them by unique values, however not sure how to then sort them. I was also wondering if there's a way to do it with a single function. I've attached what the function returns in it's current state.

const countUnique = arr => {
const counts = {};
for (var i = 0; i < arr.length; i++) {
counts[arr[i]] = 1 + (counts[arr[i]] || 0);
};
return Object.entries(counts).sort((a, b) => a[1] > b[1] ? -1 : 1).reduce((result, [key, value]) => {
result[key] = value;
return result;
}, {});
};
