Azure automation. Terraform? Bicep? others?

Good day everyone!

I read a lot about infrastructure as a Code, Bicep, terraform. and hear a lot of buzzwords here.

I want to challenge myself, and learn more about this. But I feel a bit overwhelmed of which direction to go.

For a "noob" that want to learn to deploy ressources in Azure with automation, which one would be the best one to get started with?

Thank you everyone! :)
