Hi @yegeto

You should destructure id , title , date , description as the parameters of the callback of your forEach() .

Destructuring using curly braces.

Happy coding

3 
taskData.forEach({id, title, date, description} => {

  })

I think I do not know how to do destructing

4

You removed the round braces.

Place a round opening brace before the opening curly brace.
Then place a round closing brace after the closing curly brace.

thank you. I do not understand the logic but it works.
