Hello. You haven't seen you for a little while? Face to face. We've been stuck behind that screen for a very long time. So this video is going to be talking about a few things. We'll talk about what Javascript does. Okay. The difference between javascript and then J query. We'll look at why we can't use CSS. Okay. Like we have been doing so far and then we'll look at alternatives for j query. Okay. There are different competing libraries. So let's jump in and talk about those. Alright, first up, what is javascript? So it's easy to understand when we compare it to what we already know. So we've got html CSS we're kind of okay with those right. Html other things. Okay there the headings that are on the page, the div tags, the boxes, the and never items. Okay. The footer. They're the things that are on the page and they don't do much. They're very static. CSS. Is the styling of those things right? We make them blue or 100 pixels wide. Okay, so we style those html blocks now where javascri...

pt fits in. It is the interaction between the website and me as a human being. Okay. Because at the moment our site doesn't really do much. You can click on links and jump around but it's not very exciting, exciting stuff is what javascript does. Okay. So when I in this particular case we're gonna be looking at creating mobile menu. Okay. And clicking on that and getting it to drop down. That's one interactive interaction. We did that in CSS though. And I'll discuss why we can't do it in this case, but that is a bit of human interaction. It might be uh an image slider. So when you click left and right, you scroll through images, we'll do that later in the course as well. That's a javascript. Making those clicks pulling in images and then sliding them off. A bit of human interaction tab menus, What else? Pop up models, gay on screens. There's all javascript. Okay, so that's what Javascript is. Now. What is J query in relation to it? Because you see it online. Lots so that they kind of get folded together. So javascript is the hardcore behind the scenes big boy version of this programming language. Okay. And that's what people use for a long time. Okay. To make all those interactive things. The image sliders and the pop up models and some clever designers, web developers decided actually two. Right, let's say our mobile menu. Okay, drop down here. We to toggle that on and off. Okay. We had to write maybe 56 lines of code to get that to work. Okay. And the thing is they, what they saw was like we're doing this every single time. Why do we have to type all this out? So what they decided is let's make this other thing will happen to call j query and it's a library of we'll take those six lines, we'll squish them all up and we'll put them into a little kind of function or a little class. Let's let's just call it toggle. Okay. So for me as a web designer, I just have to say the little icon for the menu. I want you to toggle. Okay. What's the browser sees? Is it sees toggles and then unpacks all of the code that's been crammed into toggle. Okay. And it reads the six lines of code. So it's just an abbreviation of the bigger programming language, which is javascript. Hope that explained it. All right. I finished that video and I figured that was an average explanation. Let's just quickly show you what the code looks like. So, I also want to show you the J. Query dot com website. So this is kind of home base for it. Okay. And you can go into the api documentation. Okay. And I'm gonna scroll these are all the different things that can do. Okay. I'm gonna score down to toggle. Let's find the regular old toggle. Okay. And inside a toggle which we're gonna use for our menu. It's going to be with the long version. So that is the long version of it. So what I say is I want this div tag called foo to toggle. The display. That's easy to write. This is what actually is happening in the javascript. You can see the syntax is easier, It makes more sense. It's not as many equals and the language is just easier to understand. So J query is just packaging this and tying it into slightly smaller, easier to understand syntax, you've got it now. Right? All right back to the unshaven dude in his red glasses. All right. One of the other things I wanted to discuss is why can't we just use CSS? Because we made a drop down menu earlier on remember? And we was for our raw bikes, a bike repair shop and we just hovered above it and the dropdown came, what can I just do that for mobile now? The main reason, well, one of the reasons is that I can't hover like grab my phone like okay, I can hover with the mouse, I can get my mouse in the hover but I can't hover with my my computer with my mouse with my phone. Right, okay. Just it doesn't know where your finger's hovering so we can't use that simple function so we have to actually click on it and CSS doesn't like to do it. Okay. It is a styling code, we can hack CSS two pieces to try and get it to do the things we want but there is like, that's what javascript is built for this kind of human interaction so we're going to use that by the city's in javascript. We're gonna cheat a little bit and use one of the libraries were gonna use J. Query in this case, that's why we can't use our sweet CSS hover or rollover. Alright, next point. Alright, last thing I want to cover is J query is just one option. Okay, so javascript is always there at the bottom. Okay, and on top of that has been built. J query. It's been around a long time. Does exactly what I needed to do as a web designer, but other smart people went, I like J crew but I want to do something slightly different so something like react is newer and it does different things for J query. So it's just a competitors. Probably not the right word, but it's just a different way of interacting with the javascript. There are frameworks like angular and Vue as well. Okay. And they're all using javascript and making it kind of easier to build other things like it's amazing what you can do with javascript in terms of SAS kind of products or in browser software. Um but yeah, that's what jay careers is one option that you can use to interact with javascript and that is it. Yes, I need to shave. Yes, I wear shorts while I'm training. What about it? Let's jump back behind the screen and build the actual menu
