00:00:08,640 --> 00:00:14,040
In this blog, we are going to talk about the long chain expression language.

2
00:00:14,160 --> 00:00:22,260
As you know, the long chain expression language is something like the version two of the Lang chain

3
00:00:22,260 --> 00:00:23,040
framework.

4
00:00:23,130 --> 00:00:23,670
Right?

5
00:00:23,670 --> 00:00:31,380
So the initial version of Lang Chain was very simple, a very useful for us to create toy demos.

6
00:00:31,380 --> 00:00:41,880
And right now they are making this effort to a go closer to the professional Elm applications and developers.

7
00:00:41,880 --> 00:00:48,480
And with that in mind, they are building this long chain expression language, which we can call the

8
00:00:48,480 --> 00:00:52,410
Lang Chain 2.0 version.

9
00:00:52,410 --> 00:00:58,140
Right now, it's not exactly that, but more or less in our opinion, this is what they are doing.

10
00:00:58,140 --> 00:01:02,460
It's like an evolution of the initial version of Lang Chain.

11
00:01:02,460 --> 00:01:08,550
So we still don't know what is going to be the future of this.

12
00:01:08,550 --> 00:01:15,960
Two different versions of Lang Chain, if they are going to live together as they are now, or if Lang

13
00:01:15,960 --> 00:01:21,150
Chain is going to promote one on top of the other, we still don't know.

14
00:01:21,150 --> 00:01:23,820
But we think Lang Chain is very useful.

15
00:01:23,820 --> 00:01:31,350
The basic version of Lang Chain is very useful to learn the concepts of Elm applications and Lang Chain

16
00:01:31,350 --> 00:01:37,470
expression language, as you will see in this blog, is an interesting evolution with advantages and

17
00:01:37,470 --> 00:01:41,610
disadvantages, as you know from previous, uh, lessons.

18
00:01:41,610 --> 00:01:44,220
But it's interesting to know about them.

19
00:01:44,220 --> 00:01:51,120
So we are going to see in this blog the main how to do with lang chain expression language.

20
00:01:51,120 --> 00:01:59,040
The main operations, uh, we have performed with the basic version of Lang Chain.

21
00:01:59,400 --> 00:02:08,940
Remember that for every detailed video in this blog you will have a the attached materials with the

22
00:02:08,940 --> 00:02:16,830
notebook, uh, with the code and the explanatory text, and also the slides of the presentation we

23
00:02:16,830 --> 00:02:18,840
use in the detailed video.
