Adding Objects to List in Javascript

Question

I'm given the following data:

Reference List:

[{

    name: "dog", present: false

}, {

    name: "cat", present: true

}, {

    name: "bird", present: false

}]

Given List:

["dog, cat"]

Wanted Result:

[{

    name: "dog", present: true

}, {

    name: "cat", present: true

}, {

    name: "bird", present: false

}]

Right now I can produce the Wanted Result by creating 3 conditional statements and performing an

indexOf

. However, I'm wondering if there's a way to do that all in 1 line through something like lodash.

Answer 1

Is that what you need?

let reference = [{name:"dog", present:false}, {name:"cat", present:true}, {name:"bird", present:false }];
let list = ['dog', 'cat'];

let result = reference.map(item => ({
  name: item.name,
  present: list.indexOf(item.name) !== -1
}));

console.log(result);

It is logically doing the same you wrote, just utilizing the .map function for that.
