WEBVTT 00:00.930 --> 00:05.580 I know that you want to start writing code soon, I promise that you will start addressing this possible. 00:06.000 --> 00:10.080 But before that, let's have a brief overview about what JavaScript is. 00:10.620 --> 00:15.210 You're starting to learn one of the most popular and frequently used programming language today. 00:15.720 --> 00:20.880 When we refer to front, end and back and web development, you may already know that there are lots 00:20.880 --> 00:28.610 of programming languages that we can use for Pachon Web development like Java, Python, C Sharp. 00:28.950 --> 00:32.730 But as for the content, JavaScript is almost the only language. 00:33.390 --> 00:38.070 It is built in old modern Web browsers and that makes it powerful and great language. 00:38.790 --> 00:46.050 But besides that, thanks to the new technology called Noguez, it can be used on several sites as well, 00:46.590 --> 00:51.600 which means that JavaScript enables back and access to databases, file systems and servers. 00:52.440 --> 00:57.990 In this course, we will talk about JavaScript as a Clydeside programming language, and our working 00:57.990 --> 01:01.920 environment will be the Web browser in 2018. 01:02.400 --> 01:08.100 All experienced developers recommend to start learning JavaScript because there are tons of libraries 01:08.100 --> 01:13.920 and frameworks like Angular JS, React, Yuji's and many others. 01:14.280 --> 01:16.900 But all of them are created based on JavaScript. 01:17.340 --> 01:21.810 Therefore, if you learn it well, you won't have any trouble to learn all those technologies. 01:22.110 --> 01:27.210 JavaScript is an object oriented programming language, which means that JavaScript is the language 01:27.210 --> 01:28.690 that is based on an object. 01:29.430 --> 01:34.980 This is important because almost everything is an object in JavaScript, but it's different from other 01:35.010 --> 01:36.810 object oriented programming languages. 01:37.290 --> 01:42.450 Throughout the course you will be able to understand all of these concepts step by step in-depth. 01:43.440 --> 01:49.230 You may already know that HTML is the markup language that developers use to create the content of Web 01:49.230 --> 01:49.560 page. 01:50.130 --> 01:57.270 So you can imagine that HTML is like the skeleton of the human, therefore styling and for design the 01:57.300 --> 02:04.050 original content we use success and it's like the human which cannot think, act or move. 02:04.560 --> 02:10.250 And JavaScript is a programming language that enables to create dynamically updating content. 02:10.770 --> 02:16.110 It's like the human which can think, act, move, run and etc.. 02:16.920 --> 02:19.950 JavaScript makes the web pages dynamic and interactive. 02:19.950 --> 02:26.280 It allows the elements to act in different ways on the page, like animations, moving text, drop down 02:26.280 --> 02:27.330 menu and so on. 02:28.480 --> 02:34.450 All right, let's talk a little about the history of JavaScript and the versions of it, JavaScript 02:34.450 --> 02:36.440 has a strange name in history. 02:36.460 --> 02:42.340 It was created by Netscape in 1995 and was called as a life script. 02:42.910 --> 02:50.200 But after a year, it was renamed as JavaScript, hoping to capitalize on Java's popularity at the time. 02:50.860 --> 02:54.550 Actually, Java and JavaScript are completely different programming languages. 02:54.980 --> 02:57.010 They do not have the relationship. 02:57.460 --> 03:05.140 In 1996, Netscape submitted JavaScript to Akima International for standardization, and eventually 03:05.140 --> 03:10.780 in 1997, ECMAScript one became the first version of JavaScript language standard. 03:11.830 --> 03:20.380 In 2009, ECMAScript five or simply iOS five, was published with lots of new and cool features, and 03:20.380 --> 03:25.830 after 2012, writing code in S5 five became much more popular. 03:27.040 --> 03:35.530 The new version of JavaScript was released in 2015 and was called as ECMAScript 2015 or yes, 2015. 03:36.040 --> 03:38.250 Today it's known as S six as well. 03:38.860 --> 03:41.150 Yes, six is the huge update of JavaScript. 03:41.170 --> 03:46.390 There are lots of new and great features added to this version, which you will definitely see throughout 03:46.390 --> 03:47.950 the course after that. 03:48.130 --> 03:55.150 Three more versions were released ECMAScript 2016, 2017 and 2018. 03:55.690 --> 03:58.390 But for now, actually, they are not widely used. 03:59.860 --> 04:00.310 All right. 04:01.520 --> 04:06.320 So in this lecture, we had a little overview of what JavaScript is, how it works and how it's used 04:06.320 --> 04:06.750 today. 04:06.950 --> 04:12.290 We have seen the difference between three Fronton technologies, which are HTML success and JavaScript. 04:12.620 --> 04:16.580 And also we had a brief overview of how JavaScript was created and developed. 04:17.360 --> 04:17.950 Let's move on.
