1

00:00:00,330 --> 00:00:06,240

So you might be asking yourself, why go or go flying, as they sometimes call it, why not some of



2

00:00:06,270 --> 00:00:08,820

the other Web development environments that exist?



3

00:00:08,820 --> 00:00:10,620

And that's a legitimate question.



4

00:00:10,620 --> 00:00:13,400

And there's nothing wrong with lots of other development environments.



5

00:00:13,770 --> 00:00:17,810

But let me give you some of the reasons why Go is such a good language.



6

00:00:18,420 --> 00:00:22,530

One of the most popular development environments right now is called Laravel.



7

00:00:22,530 --> 00:00:23,690

And there's nothing wrong with that.



8

00:00:23,700 --> 00:00:24,030

No.



9

00:00:24,030 --> 00:00:28,770

James has a great runtime that allows you to write your applications in JavaScript, both on the client



10

00:00:28,770 --> 00:00:30,270

side and on the server side.



11

00:00:30,660 --> 00:00:35,070

And there are many other frameworks and environments that you might choose to work with.



12

00:00:35,370 --> 00:00:38,250

But Go has some significant advantages over those.



13

00:00:38,250 --> 00:00:39,090

In my opinion.



14

00:00:39,330 --> 00:00:42,560

To start with, Go is a compiled language.



15

00:00:42,570 --> 00:00:47,970

It's not an interpreted language, for example, is an interpreted language, which means every time



16

00:00:47,970 --> 00:00:54,930

that you hit a page on a site built in AP, it has to load that page into memory, run it through the



17

00:00:54,930 --> 00:01:01,590

interpreter, and then execute the necessary requite or code and send the page to the end user.



18

00:01:01,920 --> 00:01:02,880

Go was compiled.



19

00:01:02,910 --> 00:01:09,870

That makes it much, much faster, in some cases as much as 200 times faster than the same operation



20

00:01:09,870 --> 00:01:10,230

done in.



21

00:01:11,670 --> 00:01:14,000

Also, there are no run times to worry about.



22

00:01:14,010 --> 00:01:19,650

So if you're using HP or you're using Python, well, you need to make sure that you have the correct



23

00:01:19,650 --> 00:01:23,030

version of AP or of Python installed on your server.



24

00:01:23,220 --> 00:01:27,420

You don't have that problem with good because everything is compiled to a single binary file.



25

00:01:27,960 --> 00:01:33,990

All of the third party packages, anything else you might use goes into a single binary file and that



26

00:01:33,990 --> 00:01:35,150

is extremely convenient.



27

00:01:36,000 --> 00:01:42,900

It's also a statically typed language, which means you can't accidentally put a date into a variable



28

00:01:42,900 --> 00:01:45,900

that's meant to hold a an integer, for example.



29

00:01:46,440 --> 00:01:50,010

Now you can do that in dynamically typed languages.



30

00:01:50,010 --> 00:01:55,130

And what that often results in is you have surprises when you run the application.



31

00:01:55,140 --> 00:02:01,500

Things don't work the way you expected because you tried to put one type of data into a variable that's



32

00:02:01,500 --> 00:02:03,450

supposed to hold a different kind of data.



33

00:02:03,810 --> 00:02:04,930

And you can't have that and go.



34

00:02:04,950 --> 00:02:08,820

You can't even compile the application if you're trying to do that sort of thing.



35

00:02:08,820 --> 00:02:11,610

So you don't have any surprises when you launch an application.



36

00:02:12,300 --> 00:02:17,580

It's also sort of object oriented and there's a fair bit of discussion about this on the Internet.



37

00:02:17,970 --> 00:02:23,940

But basically it's a language which has some of the elements of an object oriented programming language



38

00:02:23,940 --> 00:02:28,080

like your Java, but it implements them using something called interfaces.



39

00:02:28,080 --> 00:02:31,170

And we'll talk more about that when we get to the interface as part of the course.



40

00:02:31,440 --> 00:02:33,900

But extremely easy to write go code.



41

00:02:34,950 --> 00:02:37,140

Also, you get concurrency out of the box.



42

00:02:37,140 --> 00:02:42,630

So if I'm running an application on a server that has, for example, eight processors, I can take



43

00:02:42,630 --> 00:02:44,820

advantage of all eight processors.



44

00:02:44,820 --> 00:02:50,430

I can have things running concurrently so I can have my application running and doing multiple things



45

00:02:50,430 --> 00:02:51,450

at the same time.



46

00:02:51,780 --> 00:02:57,710

Whereas JavaScript and P for the most part are single threaded application programming languages.



47

00:02:57,840 --> 00:02:59,570

You can only do one thing at a time.



48

00:02:59,580 --> 00:03:05,400

Now, to be fair, there are ways around that, but it's jumping through an awful lot of hoops to accomplish



49

00:03:05,400 --> 00:03:07,470

something that you get out of the box with.



50

00:03:07,470 --> 00:03:14,400

Go Go can also be compiled for the Mac, for Windows, for Linux and for many other operating systems



51

00:03:14,820 --> 00:03:16,710

without any difficulty whatsoever.



52

00:03:17,160 --> 00:03:23,280

And finally, Go has excellent package management, far superior, in my opinion to say composer in



53

00:03:23,280 --> 00:03:24,240

the world.



54

00:03:24,480 --> 00:03:27,600

And it has excellent testing functionality built into it as well.



55

00:03:27,810 --> 00:03:31,800

And will we get to the testing part of the course and the package management part of the course will



56

00:03:31,800 --> 00:03:35,610

discover just how effective and how well written these things are.



57

00:03:36,060 --> 00:03:40,560

Finally, go is incredibly concise and very, very easy to learn.



58

00:03:40,800 --> 00:03:46,680

And it was built from the beginning, right from the outset, to be aware of the web of the Internet.



59

00:03:46,830 --> 00:03:51,510

And it takes advantage of lots of things that you don't find in other programming languages.



60

00:03:51,510 --> 00:03:58,020

For example, while you can run a Web server in EPEAT, it's not a very good one and you can't have



61

00:03:58,020 --> 00:04:01,380

more than two or three people accessing the site at the same time where it crashes.



62

00:04:01,980 --> 00:04:08,370

Whereas in go you have a Web server built right into the standard library, which is production ready.



63

00:04:08,370 --> 00:04:13,380

It will handle thousands of simultaneous users provided that you have a server that can handle that



64

00:04:13,380 --> 00:04:14,100

kind of traffic.



65

00:04:14,460 --> 00:04:16,680

But it's a great language to work with.



66

00:04:16,680 --> 00:04:19,830

It's easy to learn and I think you're going to enjoy it a great deal.
