Eclipse vs Jest

UPDATE: Thanks for the great response. I am going to start with VSCode based on the open source and free version that will allow me to grow into other languages, but not cost me a license ..yet.

I have been working with software development for 12 years, but I am just beginning my journey to learn to code. I am starting with Python following the suggestion of some of my coworkers. They are split between Eclipse and IntelliJ IDEA for IDEs that they use and PyCharm is new to me. Which IDE would you suggest for a beginner that will allow expansion to Java, JavaScript, and eventually AngularJS and possibly mobile applications?

I originally chose IntelliJ over Eclipse, as it was close enough to the look and feel of Visual Studio and we do go back and forth between the two. We really begin to love IntelliJ and their suite of IDEs so we are now using AppCode for the IOS development because the workflow is identical with the IntelliJ. IntelliJ is super complex and intimidating at first but it does afford a lot of nice utilities to get us produce clean code.

As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.
