Modern Lists in SharePoint come with one pre created view All Items.

You can create your own personal views as a way of organising information in a list. A personal view is only visible to yourself.

List or site owners can create custom public views which have the same design options as personal views however, they are available to all list users.

In Modern Lists you can edit the view just in time, with the option to save the view by clicking Save view from the Views dropdown.

You can also quickly arrange data by sorting and filtering columns.
