Intro to JavaScript - Full Stack Web Dev Bootcamp Day 4 (2024-06-20)

After learning HTML and CSS, we jump into the JavaScript programming language in the context of manipulating web documents.
We learn how to find elements in the document with JavaScript through the document object. If we assign an id to an element, we can find it with JavaScript using the getElementById function from the document object.
We learn how to change the style with JavaScript.
Then we learn how to manipulate HTML element attributes, like the src attribute of an img tag.
We learn to listen to events. In particular, we learn to add an onclick event listener to perform a setup of instructions when clicked. We learn to define a function and call it when a button is clicked.
We also learn how to play an audio player using JavaScript. We hide the audio player and make a sound when a button is clicked.
We also learn to find elements in the document using other functions such as querySelector.
