Aside from all the great resources that AstonJ provided, I’d say start coding.

I’ve been coding for 20 years and I’ve never really learned any technology from reading beforehand. Just start coding, reading docs when you get stuck, and ask questions.

Have you seen our Learning Resources > Books and Learning Resources > Courses sections and Learning Resources > Screencasts? There are some amazing resources listed there. You can also see reviews by members too

This is also a good section worth browsing as lots of similar questions have been asked previously - take a look here #learning-resources:learning-questions

Aside from that, if you could give us more details about your level of experience, what kind of apps you want to develop etc, we might be able to point out something more specific for you

I didn’t watch these personaly, but could be useful for your needs.

My main purpose to learn elixir is to build a web chat app,is there any resources particular to that?
and thanks for the links

Look at the channels doc page for phoenix, it has a chat app as an example.
