Excel online at last back in 2015 was writing in script#. Not only c# IDE support was just miles ahead (that's per vscode, typescript days), the biggest thing was the ability to author unit tests that leverage lots of work from at the time dedicated testing organization. (Who wrote unit tests in js 10yrs ago, anyone? )

:raises-hand: - I was certainly writing unit tests in JS in 2012. Jasmine came out in 2010 and was already widely adopted.

Also, Jasmine wasn't the first test runner by a long shot (John Resig wrote one for jQuery before Jasmine was a thing and there were earlier ones too).
