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'}
]
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
