2
00:00:04,983 --> 00:00:08,220
Welcome to Getting Started with ES 2015.

3
00:00:08,220 --> 00:00:12,620
JavaScript is an evolving and changing
language that's routinely updated and

4
00:00:12,620 --> 00:00:14,000
improved upon.

5
00:00:14,000 --> 00:00:16,227
ES 5, short for ECMAScript 5,

6
00:00:16,227 --> 00:00:20,451
was long the version of JavaScript
supported in web browsers.

7
00:00:20,451 --> 00:00:24,971
And if you've taken our JavaScript basics
and loops, arrays and objects courses,

8
00:00:24,971 --> 00:00:27,083
that's the version you've learned.

9
00:00:27,083 --> 00:00:31,875
ES 2015, also called ES 6, is a newer
version of the language that's now

10
00:00:31,875 --> 00:00:35,738
well supported in browsers and
commonly used by programmers.

11
00:00:35,738 --> 00:00:40,302
If you've learned ES 5 don't worry,
most of the language is the same but

12
00:00:40,302 --> 00:00:44,953
there are parts of ES 2015 that you
should learn and start using today.

13
00:00:44,953 --> 00:00:45,887
In this course,

14
00:00:45,887 --> 00:00:50,426
we'll revisit some of the concepts we
teach in our JavaScript basics and loops,

15
00:00:50,426 --> 00:00:55,183
arrays, and objects courses including
the ES 2015 way of creating variables.

16
00:00:55,183 --> 00:00:57,926
Another way to create and
concatenate strings and

17
00:00:57,926 --> 00:01:01,329
a different way to write functions
known as arrow functions.
