TRANSCRIPT

Hello everyone, my name is Laghu Pieris, and welcome to the jQuery course. jQuery is the most used java script library in the world because, it does operations that are very very basic We do things like searching for elements, changing element values and adding classes so, things that are used whenever you are performing web development work that are not included by the full in Javascript. With jQuery you can also perform rich interactions. You can perform click events, you can listen for whenever you change values in a forum, in a drop down menu. And, we're also going to be able to work with data. Whenever you're working with jQuery and whenever you're working with web development in general, you need to keep in mind something called DOM. This is D-O-M. Document Object Model. It's kind of the base object whenever you're working with the web. So, we have a DOM for this image. For this text here. For this style. For this paragraph. So, there are objects everywhere in the web page and, we need to be able to know how to manipulate all of these objects. There's some requirements to learn this course, even though something, this is going to be a very light introduction. You need to know how to work with HTML. Something very basic, very introductory. You also need to know how to work with CSS. Javascript is essential because well, we're going to work with Javascript to be able to communicate with jQuery. And, you also need two, at this point, two different pieces of software. You need to have Google Chrome installed and, you're also going to need a code editor. We're going to use an open source one, okay, a free one to use, which is Atom. Another very important link for you to have open at all times, whenever you're developing with jQuery, is api.jquery.com. So, now that we have gone through this introductory lesson, We're now going to move to the next video where we're going to set up our entire environment and work with jQuery. See you soon.
