Having trouble with the lodash find function in my Angular application

Question

Having trouble with the lodash find function in my Angular application

npm install lodash
npm install @types/lodash

ng serve

import { find, upperCase } from 'lodash';

console.log(upperCase('test')); // 'TEST'
console.log(find(items, ['id', id])) // TypeError: "Object(...)(...) is undefined"

I experimented with different ways of importing lodash and also tried avoiding the use of _.matchesProperty iteratee shorthand, but unfortunately none of these solutions seemed to work.

Despite searching extensively, I am unable to locate any resources or tutorials that outline any additional steps required when incorporating lodash into an Angular project.

Angular CLI: 8.2.2
Node: 10.14.1
OS: win32 x64

The lodash-es package is what we have implemented, allowing us to import individual functions for use.

Installation:

yarn add lodash-es @types/lodash-es
// or
npm install lodash-es @types/lodash-es

Implementation:

import map from 'lodash-es/map';

const result = map(someArray, function(item) {
  return item * 2;
});

To effectively integrate loadash with Angular, follow these steps:

Begin by installing loadash

npm install --save lodash
Next, install the typings
```
$ npm install --save-dev @types/lodash
```
Now import loadash into your project

import * as _ from "lodash";

Alternatively

import _ from "lodash";

Execute the example as shown below:

const items =[{id: 10, name: "Alex" }, {id: 20, name: "Jane"}];
console.log(_.find(items, ['id', 10]));

The expected output for this program is:

{id: 10, name: "Alex" }
