how to use the reject function from the lodash library in typescript

To use the reject function from the Lodash library in TypeScript, you need to first install the Lodash library into your TypeScript project:

npm install lodash

Then, you can import the reject function from Lodash and use it like this:

index.ts
import _ from "lodash";

interface User {
  name: string;
  isAdmin: boolean;
}

const users: User[] = [
  { name: "Alice", isAdmin: true },
  { name: "Bob", isAdmin: false },
  { name: "Charlie", isAdmin: true }
];

const nonAdminUsers: User[] = _.reject(users, { isAdmin: true });
console.log(nonAdminUsers);
// Output: [{ name: "Bob", isAdmin: false }]

In this code, we define an interface User to represent the objects stored in the users array. We then define an array of User objects.

We use the reject function from Lodash to filter out the User objects whose isAdmin property is true and store the result in the nonAdminUsers array. Finally, we log the nonAdminUsers array to the console.

Note that the second argument to the reject function is an object that defines the properties to filter on. In this case, we filter on the isAdmin property and select all objects whose isAdmin property is not true.
