Using Lodash to eliminate objects from a list

I have a specific model for my list, it looks like this:

Animal Model

    id
    name
    age
    gender
    city

Within the animals[] = []; array that I am working with, I need to remove the fields name, age, and gender while keeping id and city. How can I achieve this?

My Attempt:

    import { pick, keys } from 'lodash';

    this.animals = pick(this.animals, keys(['name,age,gender']));

Error Message Received:

[ts] Type 'PartialDeep' is not assignable to type 'Animal[]'. Property '[Symbol.unscopables]' is missing in type 'PartialDeep'.

Answer №1

A brief explanation of Lodash's pick function:

Generates a new object by selecting specific properties from the original object.

If your data is stored in an array called this.animals, you can achieve the desired outcome with the following code snippet:

this.animals.map(animal => pick(animal, keys(['name, age, gender'])));
