In this Javascript tutorial for beginners, we're going to be using Javascript selectors to access the DOM (document object model) and interact with our webpage in realtime. Selectors allow us to search for elements in the web page, get those html elements, and do things with them.

Selector methods are:
document.getElementsByTagName('div')
document.getElementsByClassName('done')
document.getElementById('my-id')
document.querySelector('#my-id')
document.querySelectorAll('.classname')

Once you have selected an html element, you can modify it:
document.getElementById('my-id').innerHTML = "new html"
document.getElementById('my-id').className = "newclass otherclass"

Hopefully you liked this javascript tutorial for beginners with examples (hopefully you like every web development tutorial I crank out)
As you can see, selectors are powerful in Javascript and even if you're a javascript beginner, you can make any and every change to your web page.
