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

To use the fromPairs function from Lodash in TypeScript, you first need to install the @types/lodash package as a dev dependency using the following command:

npm install @types/lodash --save-dev

Once the package is installed, you can use the following code to import the fromPairs function and use it:

index.ts
import { fromPairs } from 'lodash';

const pairs = [['a', 1], ['b', 2], ['c', 3]];
const obj = fromPairs(pairs);

console.log(obj); // { a: 1, b: 2, c: 3 }

The fromPairs function takes an array of key-value pairs and returns an object composed from key-value pairs. In the above example, the pairs array contains three arrays with two elements each, representing key-value pairs. The fromPairs function then creates an object with the keys and values from the arrays.

This code assumes that you have already installed the lodash library, either as a direct dependency or as a dependency of another package such as react. If you haven't installed Lodash yet, you can do so by running the following command:

npm install lodash --save

Finally, to use this code in a Node.js environment, you would need to make sure you have Node.js installed and that you include a reference to the Lodash library in your Node.js application.
