Hi<p>We haven&#x27;t measured the actual time. I would say the time learning Elixir has not been a hurdle or anyway limiting factor to the projects we are working on.<p>We basically switched as a company from writing servers in C#&#x2F;nodejs&#x2F;python to just Elixir. Did this gradually during end of last year and this spring.<p>Though I must mention that all of our developers were already familiar with multiple languages. And since we have multiple projects going on we can transfer knowledge easily. So YMMV.
