Javascript To Do List, Checkbox, strike, and edit/delete items

image1 I need to make this checklist program with html, css, and javascript (without using jquery). I have been looking around for solutions, but none of them fit the criteria for this assignment. Image of example attached.

Criteria:

• When the user enters a task in the "To-do" textbox and clicks the add button, it will get added to the list

• If they type a task and hit the enter key, it will also get added to the list

• If the user checks the checkbox next to a task, the system will cross-out the task to mark it as completed

• If the user clicks the delete link next to a task, that task will be removed from the list

• If the user clicks the edit link next to a task, the task will become editable

• The user will be able to save their edit by hitting the enter key

• If the user refreshes the page, the task list will be cleared
