It seems really questionable to take on ANY new language if you're trying to build a business. If you're building a gaming business, you had better use C++, C, or C#. If you're building a business that might need to use the cloud, look at the supported languages where your chosen cloud has an sdk and pick one of those. If you're building something for Windows avoid programming languages that only have Unix implementations. Etc. Other choices are just onboarding unnecessary risk.
