Functors In JavaScript Space.

Functors are fancy terms in functional programming field. People from FP (like Haskell) background talks a lot about Functors in their day to day activities, however we as JavaScript developers, using Functors internally in all our application code base! Can't believe? Yes, we are using them without realizing! In this talk, we are going to create our own Functors in JavaScript and understand how real world use cases are solved by using Functors in JavaScript space.

Hello all, I'm in the process of learning Postgres and I find it very hard to find a resource where postgres is explained in terms of developer. Since I'm in the process of reading and applying it in my side project; I treat this gist as my knowledge sharing place on Postgres and its features. Each sub-heading tries to explain the concepts of Postgres with simple example. I may be wrong at times here, if so please free to comment.

All the codes are written and run on psql

I would be adding many stuffs as I learn them. There is no particular order in which I add the contents.

I'm using the following postgres version:

SELECT version();
