Programmieren lernen (Hobbymäßig)?

(…) there should be different scripting languages with which it would be best to start with?

You are probably well advised with JavaScript or Python. You can get in both well, there is a large community and accordingly a broad arsenal of learning material. They are also represented in many different areas or are suitable for many different scenarios.

For example, JavaScript is preferably used on the web, but can also be used for the development of mobile apps, ML and data evaluation, games and small desktop applications.

Python is good for ML and data analysis/evaluation, small desktop applications, glue software, task automation, games, (server-side) web applications, and IoT/Embedded Systems (Bsp.: Raspberry Pi).

These listed lists are certainly not complete, but should give you good approaches to what you could deal with later.

(…) and perhaps tell me how best to do it?

First look, which one of the two is most likely to appeal to you (observing the field of application). If you have a certain idea yourself (e.g.: I want to program Microcontroller), then you should check which programming language is suitable for this.

Then focus on familiarising yourself with the basics of the language you choose (including language features such as variables, operators, arrays/lists, control structures, OOP) before you start individual projects (e.g. the construction of a mobile app). Take your time and don’t rush through themes. Generally, you should expect that for this first step you need months rather than just a few days/weeks.

First, find suitable learning material and set up an environment where you can practically program. I will continue to focus on JavaScript/Python only in this answer.

(1) The first recommended entry point in any technology (be it a programming language, a framework, etc.) is the official online presence. You will usually find a documentation, the latest information and more often reference sources (recommended literature, tutorials, etc.).

For Python this would be python.org, for JavaScript you can (representative) MDN Docs look.

Other recommended learning sources can be books (e.g. book publishers such as Apress, O’Reilly, packs, Rheinwerk, Springer), video courses (view on PluralSight or Udemy) and learning platforms (e.g. Codecademy, Hyperskill, Udacity). Find out in advance by means of reviews/reviews whether a book/course tends to be worthwhile or not and also respect the year of publication or which language version it is treating. For JavaScript I would recommend as minimum start ES6 (2015), for Python from 3.9.

With other online sources (e.g. YouTube tutorials), some caution is required, as it is often difficult to evaluate whether it is actually worthwhile or not already outdated. From crash courses I can generally guess and if you notice that you have encountered a drop-off course (where the tutor does not explain its approach and functionalities used in detail), I would also recommend a change. In addition, using several sources as a source of reference is not wrong, because they can complement each other.

In addition to the platforms already mentioned, I can bIn relation to Python, especially the courses on Hyperskill and RealPython (a platform that includes articles on the most varied tools or application areas of Python). With regard to JavaScript you can look inside of me.

2) The sooner you set up a development environment with you, the sooner you can start trying out practically. I think it is the best way to handle theory and practice approximately parallel. This makes it easier to embossed the learned.

Good development environments for Python are PyCharm, Visual Studio (with the Python Development Tools) or a suitably configured Visual Studio Code (Setup Guide).

For JavaScript, I would also like to use Visual Studio Code (Setup Guide) refer. If you want to build web applications, you also need an internet browser.
