javascript - How to use lodash to find and return an object from Array? -

my objects:

[     {         description: 'object1', id: 1     },     {         description: 'object2', id: 2     }     {         description: 'object3', id: 3     }     {         description: 'object4', id: 4     } ] 

in function below i'm passing in description find matching id:

function plucksavedview(action, view) {     console.log('action: ', action);     console.log('plucksavedview: ', view);  // view = 'object1'      var savedviews = retrievesavedviews();     console.log('savedviews: ', savedviews);      if (action === 'delete') {         var delete_id = _.result(_.find(savedviews, function(description) {             return description === view;         }), 'id');          console.log('delete_id: ', delete_id); // should '1', undefined     } } 

i'm trying use lodash's find method: https://lodash.com/docs#find

however variable delete_id coming out undefined.

update people checking question out, ramda nice library samething lodash does, in more functional programming way :) http://ramdajs.com/0.21.0/docs/

the argument passed callback 1 of elements of array. elements of array objects of form {description: ..., id: ...}.

var delete_id = _.result(_.find(savedviews, function(obj) {     return obj.description === view; }), 'id'); 

yet alternative docs linked to:

_.find(savedviews, 'description', view);
