Javascript - Introduction

Building web applications requires that you have an understanding of a number of programming languages. Python is a "back end" language that runs on the server and interacts with API's, Databases and the Servers Operating System. The language that makes Web Applications interactive is called JavaScript.

JavaScript allows a web page to dynamically change based on user activity in real time. You use JS to verify what the user puts into HTML forms appears to be correct. It allows aspects of the page to change based on events such as when a user clicks on something, releases a click, focuses on and more.

We'll learn about the DOM (Document Object Model) and explain the basics of giving a web app the ability to respond to users.

The class will go over:
- What is Javascript
- What is the DOM
- Javascript Events
- Javascript Methods
- Why Javascript is a great tool, and why it can be a bad one...

back to you, Eli, after many years and so so happy. I was afraid you might have stopped making these. Now I had to recommend a good tutor online for a friend and just tried my luck at searching you and here you are! Thank you.

As a software developer with 30+ years of experience it's actually really good to be reminded of the basics.
Largely because nowadays I use React and other frameworks which abstract the DOM even further.

LOL, from Louisiana, can confirm. New Orleans never recovered from Katrina. Nor did any of the cities within a half-day drive from New Orleans.

Dude, your logic is awesome. Rossman got you though! You guys are both awesome. Honestly, I benefit more from you than him. I know it's some old hamburger meat, but you guys are awesome. Thanks. Dude, do a 'RAWR'! You found your marbles. Every single one of them, but now you've collected gems. Thanks.

Minification is still a thing and is used as an indirect way of obfuscating code too.
Many libraries do this such as Fusion Charts.
