# Node.js on Apple Silicon
Node Version Manager (https://github.com/nvm-sh/nvm) works perfectly across native node installations as well as emulated Rosetta installations.
The trick I am using here is to install one LTS version of node under Rosetta and another stable version as native binary.

## TODO
- find a way how to run the same node version on both platforms

# 2.3. Debugging Bash scripts
## 2.3.1. Debugging on the entire script
When things don't go according to plan, you need to determine what exactly causes the script to fail. Bash provides extensive debugging features. The most common is to start up the subshell with the -x option, which will run the entire script in debug mode. Traces of each command plus its arguments are printed to standard output after the commands have been expanded but before they are executed.

This is the commented-script1.sh script ran in debug mode. Note again that the added comments are not visible in the output of the script.

```
