id attributes not unique

[andy-mc-donald]

Lighthouse says:

[id] attributes on the page are not unique
Failing elements: ul#todo-block

I think what's happening here is you've set <ul id="todo-block"></ul> on line 15 of the <index.html> file.

Then in the dom.js file you're referencing it on line 62:

var todoBlock = document.getElementById("todo-block"); `

But then also setting the same id attribute in line 84:

todoListNode.setAttribute("id", "todo-block");

Could get around this by using class instead of id?
