Hey @indracahyae. Can you please explain what does datas represent in "datas.map()" at @7:18 . Is this the datas array of state or datas array from the fSubmit() function? When i do the same it says datas is not defined.

hey bro, nice tutorial, but i want to ask, how to pass index to method if the index is from other component ?
Since in your tutorial you map the data and get the index for delete and edit method in the same component.

Currently i map the data from other component, and when i create delete and edit, the index will return as undefined
