These two methods can help you to add interaction using which user can interact with your web page
1. alert()
2. prompt()
{ 9 / 20 }
alert() - display a dialog with an optional message, and to wait until the user dismisses the dialog
prompt() - display a dialog with an optional message prompting the user to input some text, and to wait until the user either submits the text or cancels the dialog

I think much JavaScript would be good enough before jumping onto DOM manipulation
Basic things you need to cover in DOM
https://abs.twimg.com/emoji/v2/... draggable="false" alt="📌" title="Reißzwecke" aria-label="Emoji: Reißzwecke"> Finding HTML Elements
- getElementsByTagName()
- getElementsById()
- getElementsByClassName()

- element.innerHTML
- element.attribute
-element.style.property
- element.setAttribute(attr, value)
- document.createElement(element)
- document.removeChild(element)
- document.appendChild(element)

Here are some advance key concepts
- Hoisting
- Closures

Although you will need an editor as you go further into this field
There are plethora of editors out there. But I would recommend VS Code. Why?
- Many built-in features
- It& #39;s fast
- Large community
- IntelliSense code completion and debugging
