Some programming languages become popular because of platform exclusivity. i.e., when there is no other languages on the same platform or they are put in disadvantage.
It doesnβt really matter how good your language is (in the reasonable bounds) when there are no other languages in the competition.
If the platform grows, the language grows as well.
Examples are:
JavaScript on the Web
Objective C and then Swift on iOS
Java/Kotlin on Android
Java on old phones
C#/.NET on Windows
