                Do we need types in JavaScript? Or maybe not?
              
          
    This is my lightning talk submission to ReactiveConf 2018 https://reactiveconf.com/

In this talk, I want to share my experience gained during the development of frontend applications in several programming languages.
I think it's not a secret for anybody that developing large JavaScript applications is not so easy as it seems at first glance. We all want something simpler and more reliable. Therefore, many developers and even entire companies switch to different, compiled in JavaScript, programming languages. The bulk of such transitions is accounted for TypeScript and flow, and often, developers faced with more problems than they were before.
I wasn't the exception. Moving to a new project, I started using TypeScript and was disappointed.
Luckily in my next project I used ClojureScript and it was like everything is illuminated!

                Install PostgreSQL 10 on Ubuntu
              
          
    Install PostgreSQL 10 on Ubuntu

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04 but likely can be used for Ubuntu 14.04 and 17.04 as well, with one minor modification detailed below.
(Optional) Uninstall other versions of postgres

To make life simple, remove all other versions of Postgres. Obviously not required, but again, makes life simple.
If you have data in your previous version of postgres that you'd like to retain, then this is not recommended. Instead, you'll have to use pg_upgrade or pg_upgradecluster.
