Solutions

Two solutions on Parking Service System, one focuses on front end, another one is implemented with Deno, which is a new experiment on this powerful backend framework.

• Parking Service dashboard: React, Typescript
• Parking Service CLI: Deno, Typescript

New Change

• Replaced .reducer() method with higher-order function Array.map() in getAllCarsBillStatement.
  • Array.reducer() is for reduction usage. While it is a very powerful method, it's not always the easiest to read or grasp at a glance. An saying: the simplest code is written sequentially.
• Replaced for loop with Array.map() in carServiceAssigner.
• Parking Service CLI - Enable the ability to log the argument data (cars, employees) and save as local data in JSON format. Note: Command updated.

Parking Service dashboard

• TODO:
  • Responsive design.
  • Enable edit feature on cars and employees.
