Take a look at either Ruby or Python - both have huge userbases in general, but are also used regularly within the business.

A lot of quick scripts are written in Python - you may have noticed this in Kali.

Ruby is what metaspoilt in built upon, meaning a lot of the modules are also ruby.

Both are great languages. In regards to where to start with learning them, take a look at https://www.codecademy.com, both are featured there and give you a nice gentle introduction to their syntax and ways of workings.

Also for Python there's https://learnpythonthehardway.org which is awesome, and https://automatetheboringstuff.com which is a little more practical to begin with.

Once you feel comfortable with the language(s), go read the source code for those scripts or modules in Kali and see what else you can pick up.
