javascript - Sorting in Underscore js -

i working on function sort list under midterm score grade ascendingly. tried ff codes:

if(score === 'midterm score'){          _.each(students, function(elem, index, list){            _.sortby(students, function(elem){               console.log(elem.midterm_score);            });           });        } 

so using elem.midterm_score did not sort list via midterm score can seen here.

i expect 90, 80, 70 , on that. idea missing? please help!

you using sortby method in wrong way. check in docs

// first of need students var students = [     {name: 'a', midterm_score: 60},      {name: 'b', midterm_score: 70},      {name: 'c', midterm_score: 40} ];  // sort midterm score , assign students variable students = _.sortby(students, 'midterm_score');  // print array in each loop _.each(students, function(el) {     console.log(el); });
