How to get distinct values from an array of objects in JavaScript?

Question

Assuming I have the following:

var array = 
    [
        {\"name\":\"Joe\", \"age\":17}, 
        {\"name\":\"Bob\", \"age\":17}, 
        {\"name\":\"Carl\         


        

Answer 1

You may be interested in unique set of objects based on one of the keys:

let array = 
[
    {"name":"Joe", "age":17}, 
    {"name":"Bob", "age":17}, 
    {"name":"Carl", "age": 35}
]
let unq_objs = [...new Map(array.map(o =>[o["age"], o])).values()];
console.log(unq_objs)
//result
[{name: "Bob", age: 17},
{name: "Carl", age: 35}]
