how to use the keyby function from lodash in javascript

keyBy function is a part of the lodash library, which is a utility library delivering consistency, modularity, performance, and flexibility to solve common programming problems in JavaScript.

The keyBy function creates an object composed of keys generated from the results of running each element of the collection through an iteratee function. The corresponding value of each key is the last element that generates the key.

Here's an example of using keyBy function in JavaScript with lodash:

index.tsx
// Importing the lodash library
const _ = require('lodash');

// Sample array of objects
const users = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Alice' }
];

// Generating an object with 'id' as the key using the keyBy function
const usersById = _.keyBy(users, 'id');

console.log(usersById);
// Output: {
//   '1': { id: 1, name: 'John' },
//   '2': { id: 2, name: 'Jane' },
//   '3': { id: 3, name: 'Alice' }
// }

In the example above, the keyBy function takes two parameters: the array of objects to be transformed and a string that represents the key to be generated from each object. In this case, the key generated is id.

The resulting object now has each user's id as its key and the rest of the object data as its value.
