OK for this section we're going to be doing JavaScript in the last section we did cover A.T.M. and CSX

which is like the trial front end web development is the Asian LCROSS and JavaScript and Javascript

is really important especially for what we're going to be doing later on with the backend stuff.

We're basically going to be working entirely with JavaScript also instead of working an atom.

We're going to be working in a different environment because an atom or I should say instead of working

with web files like actual H.G. files I'm going to be working in a rebel.

What that means is just like a javascript like a console where you could just type in code and just

execute instantly because when you're writing in for a Web site when you're writing your javascript

in your and your HMO you would have to write your javascript and then go to your web page and then reload

your web page and inspect it and see your results in your in your browser what we're going to be doing

in this section is going to be a lot quicker than that.

So what you want to do is I have a bookmark here.

But you just want to go to rebel replicate I.T. you just go to rebel dot I.T. and it should look a bit

like this.

I'm not I don't think you'll have to create a new account and then you want to go to New Rebel and there

is node which is what we're going to be using.

And there is there is a bunch of environments here that you could users a Schimmel CSX javascript we're

not going to be doing that and that here there is a javascript one to see you can go to javascript but

if you go to create ripple

you could see it's still node because node is oh does this cause node is basically just a javascript

it's basically what Google Chrome uses to execute your javascript it's the V8 engine anyway so once

you're here you could basically just write any javascript code you want right here and then you can

click Run and it will show you your results of your javascript over here on the right side.

So if we just click Run it going to return undefined which is normal.

That's what you expect.

So before I end this video I just want to show you one thing before we really started doing javascript

is the console dot log function.

We're going to be using this basically if you're if you use javascript a lot you'll use this all the

time for debugging.

So it's it's a really important thing to know.

So you just inside here inside the log you just put whatever you want to be logged.

So you put two quotes and inside the quotes you could put text whatever you want.

So we're just gonna say

javascript and then you click Run and it will put javascript there and if you put just a number like

this and click Run it along the number if you try putting some letters in there that's not going to

work because these letters are only valid when they're in a string.

So up here we can put letters loops I should have to comment this.

We could put letters here because they're inside the quotation the quotation marks which basically is

a string in Java.

It's a very it's it's just a type is what you'd call even though javascript doesn't really have types.

It still has somewhat a type.

So there's numbers the strings and there's billions.

And that's where we're going to cover more in depth in the next video.

So if this video the only real takeaway is this environment here that we're working in and also the

console log.

OK.

So that's going to be it for this video.
