hi @jmfayard I would like to post some samples on this can you let me know what are your expectations ?

[jmfayard]

Nice @ch8n !
In this ticket, the expectation is to focus on Arrow Types
https://arrow-kt.io/docs/datatypes/intro/

The challenge for this one is that Arrow does a lot of things,

1. some which are pretty advanced,
2. others who can be useful on a day to day basis.

In the sample we want to keep it simple and useful, so you have to focus on 2)

People who want to go deeper with Arrow can always do that in their own branch

hi, @jmfayard thanks for the quick response, I'm new with Arrow and I will start off with my research asap, it would be helpful if you could name certain operators that you use in your workflows.

This is one of the libraires I would like to discover but don't know well myself.
Are you in the kotlinlang slack channel?
You could ask the arrow guys there what they recommend to get started with.
Or just take another issue

currently, I'm looking into it I will update you if I'm not able to complete it, but if you have someone who is interested in this task involve him in the conversation we can collab and write some examples.

@jmfayard I'm trying to include core-arrow libs,
I have added dependencies as below but nothing is showing up, am I missing something ?

//build.gradle.kts

repositories {
    // arrowKt
    maven(url = "https://dl.bintray.com/arrow-kt/arrow-kt/")
    maven(url = "https://oss.jfrog.org/artifactory/oss-snapshot-local/")
}

dependencies{
..
implementation("io.arrow-kt:arrow-core:_")
implementation("io.arrow-kt:arrow-syntax:_")
}

@ch8n We won't use snapshots so you don't need maven(url = "https://oss.jfrog.org/artifactory/oss-snapshot-local/")
Apart from that, I've tested it locally and it worked
Just make sure to do a Gradle Sync

By the way, there is a section Katas and exercises at https://arrow-kt.io/docs/quickstart/projects/
Might be a good source for inspiration

hi @jmfayard I have been learning arrow core and did some of the examples from docs but I'm not getting feel that these examples im adding will have any value for someone learning

please can you do code review of what all I have added uptill now?
