how to use the frompairs function from lodash in javascript

The fromPairs method from lodash allows you to create an object from an array of key-value pairs. Here is an example of how to use it:

index.tsx
const _ = require('lodash');

const pairsArray = [['a', 1], ['b', 2], ['c', 3]];

const obj = _.fromPairs(pairsArray);

console.log(obj); // Output: {a: 1, b: 2, c: 3}
168 chars
8 lines

In this example, we first require lodash and define an array of key-value pairs. We then pass this array to the fromPairs method and assign the resulting object to the obj variable. The output of the program when we log obj to the console will be:

index.tsx
{a: 1, b: 2, c: 3}
19 chars
2 lines

This is a simple example, but fromPairs can be very useful when working with dynamic data structures that need to be transformed into objects in a functional and concise way.
