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 have to reset the peopleMostNeedingHelp when a new student with a higher number of errors is discovered:

let mostNeedingHelp = [students[0]];

for(const student of students.slice(1)) {
  if(student.errors === mostNeedingHelp[0].errors) {
    mostNeedingHelp.push(student);
  } else if(student.errors >= mostNeedingHelp[0].errors) {
    mostNeedingHelp = [student]; // <<<<
  }
}

This can be shortified with reduce:

const mostNeedingHelp = students.slice(1).reduce((arr, student) => 
 arr[0].errors === student.errors ? arr.concat(student) : arr[0].errors < student.errors ? [student] : arr, [students[0]]);
