I found this solution:

var collections = [
    {name: 'somename1',  desctiption: 'xyz'}, 
    {name: 'somename',   desctiption: 'ds'},
    {name: 'somename',   desctiption: 'rtrt'},
    {name: 'somename2',  desctiption: 'nhf'},
    {name: 'somename1',  desctiption: 'qwe'}
];

names = ['somename1', 'somename2']

_(collections)
    .keyBy('name')
    .at(names)
    .value();

But the result contains only one value with somename1, how can I get all values with somename1?

• javascript
• underscore.js
• lodash

If by all values you mean the objects, then

const values = collections.filter(e => ['somename1', 'somename2'].includes(e.name))

If you mean the description, then

const descriptions = values.map(e => e.description)

For this kind of stuff you don't really need lodash anymore.

You can use find method to get one value

_.find(collections,{name : 'somename1'})

For all objects with somename1

_.pullAllWith(collections,{ name : 'somename1'})

Console.log the results are as expected
