1.	What is UUID, and how you can generate it in Node.js?
Answer» A UUID is a Universal Unique Identifier is a method for generating ids that have been standardized by the Open Software Foundation (OSF). You can generate UUIDs in Node.js through the node-UUID. It is a speedy and straightforward way of generating VERSION 1 & 4 UUIDs. Here's how to generate UUIDs Install the node-uuid through the npm manager using npm install uuid. Use it in your script like this: CONST uuidv1 = require('uuid/v1') const uuidv4 = require('uuid/v4') var uuid1 = uuidv1() var uuid5 = uuidv4() Here is how your OUTPUT would look. ALTHOUGH, due to the nature of UUIDs, your GENERATED IDs may be completely different. Output uuid1 v1 => 6bf958f0-95ed-17e8-sds37-23f5ae311cf6 uuid5 v4 => 356fasda-dad8d-42b7-98b8-a89ab58a645e
