 1. To begin, download a copy of our [shopping-list.html](https://github.com/mdn/learning-area/blob/main/javascript/apis/document-manipulation/shopping-list.html) starting file and make a copy of it somewhere. You'll see that it has some minimal CSS, a form with a label, input, and button, an empty list, and a {{htmlelement("script")}} element. You'll be making all your additions inside the script.
 2. Create three variables that hold references to the list ({{htmlelement("ul")}}), {{htmlelement("input")}}, and {{htmlelement("button")}} elements.
 3. Create a [function](/en-US/docs/Learn_web_development/Core/Scripting/Functions) that will run in response to the button being clicked.
-4. Inside the function body, start off by calling [`preventDefault()`](/en-US/docs/Web/API/Event/preventDefault). When wrapped in the form element, the input will trigger the form to submit when the user presses the <kbd>Enter</kbd> key. This will keep the form from refreshing the page and will add a new item to the list.
-5. Continue by storing the current [value](/en-US/docs/Web/API/HTMLInputElement/value) of the input element in a variable.

Since the input is wrapped in a form element, pressing the <kbd>Enter</kbd> key will trigger the form to submit. The call to `preventDefault()` will prevent the form from refreshing the page so a new item can be added to the list instead.
+5. Continue by storing the current [value](/en-US/docs/Web/API/HTMLInputElement/value) of the input in a variable.
 6. Next, empty the input element by setting its value to an empty string — `""`.
 7. Create three new elements — a list item ({{htmlelement('li')}}), {{htmlelement('span')}}, and {{htmlelement('button')}}, and store them in variables.
 8. Append the span and the button as children of the list item.
