how to use the mapkeys function from lodash in javascript

To use the mapKeys function from lodash in JavaScript, first you need to install lodash in your project. You can do this using npm by running the command:

index.tsx
npm install lodash

Then, in your JavaScript code, import the mapKeys function from lodash:

index.tsx
const { mapKeys } = require('lodash');

The mapKeys function takes two arguments: the object you want to map, and a mapping function that transforms the keys of the object. Here's an example usage:

index.tsx
const myObject = { a: 1, b: 2, c: 3 };
const keyMapper = (key) => key.toUpperCase();
const result = mapKeys(myObject, keyMapper);

console.log(result); // { A: 1, B: 2, C: 3 }

In this example, we define a simple object myObject with three key-value pairs. We also define a mapping function keyMapper that transforms keys to uppercase. We then call mapKeys with myObject as the first argument and keyMapper as the second argument, and assign the result to result.

The output will be a new object with the same values as myObject, but with keys transformed according to the keyMapper function.

Note that mapKeys creates a new object and does not modify the original object.
