Pros
Pro Built in Version Control
Since Version Control features are very frequently used these days, having them built right into your IDE seems quite the right thing to do. With Komodo, you can perform your Git push-es and pull-s right while you're coding.
Pro Collaboration tools
If you're working with a remote dev team, you'll quickly realize the importance of code collaboration while programming. With the Komodo IDE you don't have to setup a separate teamviewer session, or even share code via dropbox with other devs. All you need is an ActiveState account (+ a partner with the KomodoIDE ofcourse) and your remote team could see LIVE and contribute to your changes in the source files of your app
Pro Great Java Support
Pro A good editor for test-driven development
IntelliJ IDEA is really easy to work with when it comes to test-driven development in Java and JavaScript/TypeScript.
Pro Great JavaScript support
Pro Markdown support with preview
Pro Supports PHP quite well
Pro Great TypeScript support
Really good support for importing classes, libraries, etc. into a typescript class. Making it easy to do TDD.
Pro Good BASH script support
Pro Angular CLI support
Pro Made by developers for developers
It can make one more efficient, but also can get one way too used to shortcuts, autocomplete, and easy debugging.
Cons
Con Not free
Komodo IDE costs you $89 for a personal license. Even though they have a Free basic version (that's also opensource), but this lacks most of the functionality that the paid version has.
Con Is not free
But it does have a free version (Community Edition).
Con Heavy
Consumes more resources than VSCode etc. But depending on your use-case, it can still be worth it for the benefits you get with this editor.
Con Autocomplete does not work while IntelliJ is indexing
But this, in general, is not much of an issue. Usually after npm install, etc.
