Remove same property value duplicate from array of objects using Lodash

May 27, 2022

I have the below array

const values = [
  {
    name: 'A',
    age: 12
  },
  {
    name: 'B',
    age: 1
  },
  {
    name: 'A',
    age: 31
  }
]

and I want using lodash remove an object from this array that has the same name, so it should return:

 const values = [
  {
    name: 'A',
    age: 12
  },
  {
    name: 'B',
    age: 1
  }
]

Using

_.uniqWith(_.isEqual, values)

only remove duplicate if the whole object is duplicated …
How can I remove using property?

>Solution :

Use _.uniqBy() the name property instead:

const values = [{"name":"A","age":12},{"name":"B","age":1},{"name":"A","age":31}]

const result = _.uniqBy(values, 'name')

console.log(result)
