What is a coding language that is easy to learn for a beginner?

What OS and what dev tools? If you want an iOS app for instance Swift FTW. If you want a ground up education in programming, then C. Quick entry might be Python.

Not sure what dev tools, I use Ubuntu cinnamon on a mac (lost macOS to a hard drive failure).

Have a look at flutter.dev. It is a multiplatform app development environment. The have instruction materials for beginners.

Python is often mentioned when this question is asked.
