I used to write my code on my pc and test it on my browser, then I started using Cloud9 and testing over the web. Now I am trying to learn Visual Studio but I would like to know what professional businesses use besides Visual Studio.
Don't use just one. Use the best one for the area of your system that you're working on.
My IDE environment:
Aptana Studio 3 for PHP
Visual Studio 2015 for C#
Android Studio for Android
Eclipse for Java
vim for all others

Use of IDE for programming is really helps you to fasten the development process. I would prefer any products from https://www.jetbrains.com/ (Jet Brains). They have wide variety of Tools which are the best tools I have ever encountered till now..... Some of them are premium version yet they have Community Editions too..
Some of them.. For Python PyCharm(https://www.jetbrains.com/pycharm/) General Programing Intellija Idea (https://www.jetbrains.com/idea/)(A lot more plugins available for this). For Javascript(Node) Webstorm(jetbrains.com/webstorm/download)
There are a lot more prodcuts from JETBRAINS that are really good.
Also a lot more plugins available for Intellija Idea that makes other programming easy.
