TASK

Description: 

Create a REST API using Node.js & Express.js for managing products. The API should support the following:

CREATE a product
READ all products
UPDATE a product 
DELETE a product

Instead of using a database to store our products, simply create a file called “products.json”
and store all the data in that file. When you create a product, append it to that file, when deleting,
find the product and update. Don’t worry about security or authentication. 

Product Model:

{
	name: String,
	sku: String,
	price: Number,
	createdAt: Date
}
