My son who started programming at 7 pretty quickly moved on from languages like Scratch and Tinker. To the extent to which he uses them at all, it’s mostly to play games that are available in them. I’m not entirely convinced that he couldn’t have just started with Javascript or Python. It’s not like learning the syntax for a for loop¹ is that much harder than arranging the blocks in one of those block languages.
