JavaScript lodash: how to zip an array of objects with values lodash array object,lodash array object contains,lodash array object

I'm looking how to zip an array of objects with values including a new key for each value using lodash. Tried with zip, zipObject and map but I don't find the key.

What I want to do is the following (avoiding to iterate manually over the arrays)

var array = [
   {a: 3, b: 42}, 
   {c: 4}, 
   {d: 12}
 ]
 var values = ['this', 'are', 'new', 'values']
 var goal = [
   {a: 3, b: 42, v: 'this'}, 
   {c: 4, v: 'are'},
   {d: 12, v:'new'}
 ]

Answer:1

You can use zipWith() to provide a custom iteratee:

var newArray = _.zipWith(array, values, function(item, value) {
    return _.defaults({ v: value }, item);
});

Note that this approach doesn't mutate the original array.
