Best Way to Get Objects with Highest Property Value

Question

I have the following multidimensional array of student objects:

var students = [
{name: \"Jack\", age: \"NYN\", attempts: 3, wrong: 2},
{name: \"Phil\", age: \"N         


        

Answer 1

You could reduce the array by checking the wrong property.

var students = [{ name: "Jack", age: "NYN", attempts: 3, wrong: 2 }, { name: "Phil", age: "NNNY", attempts: 4, wrong: 3 }, { name: "Tom", age: "", attempts: 0, wrong: 0 }, { name: "Lucy", age: "YYNY", attempts: 4, wrong: 1 }, { name: "Ben", age: "NYNN", attempts: 4, wrong: 3 }, { name: "Hardest", age: "NNN", attempts: 3, wrong: 3 }],
    topWrong = students.reduce((r, o) => {
        if (!r || o.wrong > r[0].wrong) {
            return [o];
        }
        if (o.wrong === r[0].wrong) {
            r.push(o);
        }
        return r;
    }, undefined);
    
console.log(topWrong);
