Get object keys for filtered values

Question

The case is simple - I\'ve got a following object:

Object {1: false, 2: true, 3: false, 4: false, 5: false, 6: false, 7: false, 8: true, 12: false, 13: false, 14         


        

Answer 1

function findKey(obj, value){
    var key;

    _.each(_.keys(obj), function(k){
      var v = obj[k];
      if (v === value){
        key = k;
      }
    });

    return key;
}
