Well, it claims to be based on a true story. But in the process of turning it into a production, there could be artistic liberties taken that might deviate slightly from the pure facts.

I know of a Ruby true story where a developer was migrating an old legacy system to a new technology stack. He decided to use Ruby as it was known for its ease of integration. He used Ruby to write scripts that could interface with the old system's data. Ruby's powerful text processing capabilities made it a breeze to parse and transform the data. Through his hard work with Ruby, he managed to complete the migration smoothly, saving the company a lot of time and resources.
I don't really know. Sometimes movies claim to be based on true stories but have a lot of fictional elements added. You could check reviews or the official description for more clarity.
