Code to refactor

About the code?

• there only 4 files, the rest of app is missing
• it uses Nette, make use of Nette 2.3+
• min supported version is PHP 7 - also make use of it

What should you do?

• work as you normally do
• send PR to improve the code in ANY way
• feel free to improve code quality, SOLID principles, standard or architecture
• give it 1 HOUR tops, nothing crazy :)

Good luck and have fun!
