The problem Better-to-do-dapp solves

Existing task(from the workshop):
have not to implement a function to delete all the tasks mark all the tasks as done in one click, in the better-to-do dapp, new features are implemented in blockchain smart contract, and the frontend developer can simply call the smart contract function to do it.
Also, the next frontend has changed some styling of the website and made it look better, even more, the dapp have added a new feature that allows the user to see how many tasks they have done and how many there are left in number which gives the user perspective on using the dapp.

To conclude(getTaskname and show task name, how many tasks is done, Delete all Task in one click, update all Task status in one click)

Challenges I ran into

1. The first challenges should be limited of time, as the beginner workshop starts very late, and this project is created on the weekend before the end of the submission date.
2. the Second challenge is Solidity, I have never used this before. And so I am getting confused about how it works, for example, in another language I like to use console.log() to print out the message or debug, but in solidity, you can not do that, and so my coding plan forced to change to another way.
3. Only me, this project implements front end, and backend( blockchain) in another, it is a full-stack development, and full-stack development with only one developer the workload is huge in my perspective.
