Charts are from different sources and thus colors are inconsistent, please carefully read the chart's legends.

Similar analysis:

• React Native vs Flutter: https://gist.github.com/tkrotoff/93f5278a4e8df7e5f6928eff98684979
• ESLint vs Oxlint: https://gist.github.com/tkrotoff/8e10c7d63f97b3480a98301af9e8a28e

Personal conclusion

After all those years maintaining this data (since 2018): React is still much more popular and continue to grow faster than alternatives; Vue dates back from 2014 and Svelte from 2016, they should have overthrown React by now.

Auto reconnect to wifi when lost connection

Before you start, make sure ip command is available on your system. In modern Linux distributions, ip replaces older ifconfig command. If net-tools package (that includes ifconfig) is not installed and you prefer using it, you can install it via sudo apt-get install net-tools.

Create script file

Use touch /home/pi/wifi-reconnect.sh to create a shell script file, with the following content:

#!/bin/bash
