  • Go because it's easy and simple, facilitates collaboration , and also it's fast, scalable, powerful.
  • Visual Studio Code because it has one of the most sophisticated Go language support plugins.
  • Vim because it's Vim
  • Git because it's Git
  • Docker and Docker Compose because it's quick and easy to have reproducible builds/tests with them
  • Arch Linux because Docker for Mac/Win is a disaster for the human nervous system, and Arch is the coolest Linux distro so far
  • Stack Overflow because of Copy-Paste Driven Development
  • JavaScript and Python when a something needs to be coded for yesterday
  • PhpStorm because it saves me like 300 "Ctrl+F" key strokes a minute
  • cURL because terminal all the way

We undertook the task of building a manufacturing ERP for small branded manufacturers. We needed to build a lot, fast with a small team, and have clear focus on product delivery. We chose JavaScript / Node.js ( React + LoopBack full stack) , Heroku and Heroku Postgres (also Heroku Redis ) . This decision has guided us to picking other key technologies. It has granted us high pace of product delivery and service availability while operating with a small team.

As developer at Applied Health Analytics we decided to create a React Native App. In terms of #IDE I'm a good fan of PhpStorm cause we have a lot of PHP in the backend, but I've definitely gave a try to Visual Studio Code and now is my primary JavaScript #IDE. I was impress how fast VS Code has become the No.1 @JavaScript Editor in the community.

Sometimes #ad-blocking addons can cause a real headache when working with JavaScript apps. Onboarding assistants (Appcues + elevio ), chat (Intercom) and product usage insight (Hotjar) have all landed on their blacklists. I guess there is a perfectly good reason for this that I just don't know.

In order to fix this, we had to set up our own content delivery service. We chose Amazon CloudFront and Amazon S3 to do the job because it has a good synergy with Heroku PaaS we are already using.

From a StackShare community member: "We are looking to rewrite our outdated front-end with TypeScript. Right now we have a mix of CoffeeScript and vanilla JavaScript. I have read that adopting TypeScript can help enforce better code quality, and best practices. I also heard good things about Flow (JS). Which one would you recommend and why?"

JavaScript Alternatives & Comparisons

What are some alternatives to JavaScript?
TypeScript
TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.
Node.js
Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
Dart
Dart is a cohesive, scalable platform for building apps that run on the web (where you can use Polymer) or on servers (such as with Google Cloud Platform). Use the Dart language, libraries, and tools to write anything from simple scripts to full-featured apps.
CoffeeScript
It adds syntactic sugar inspired by Ruby, Python and Haskell in an effort to enhance JavaScript's brevity and readability. Specific additional features include list comprehension and de-structuring assignment.
Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
