> So the mainstream languages are...: C/C++, C#, F#, Go, Groovy, Java, JavaScript, TypeScript, Kotlin, Objective-C, PHP, Python, Ruby, Scala, SQL, Swift, VB.NET
Of those 18 languages, only 13 are in the TIOBE top 50. Two of them (Apache Groovy and TypeScript) don't appear in the TIOBE top 50 so it's pushing credibility to call them "mainstream" languages -- the Java-ecosystem bias is more than "only slight".
