It feels rather stupid to make up this category of "React SSGs" and then list a bunch of them that don't use React at all. And even more, wrapping up with "React is the first choice for SSGs" and "dominates the market" is absolutely ridiculous as a conclusion.
This pointless article is little more than an excuse to insert -4 times- a link to your website offering "React developers".
But of course, this is EchoJS. This is the kind of thing that is welcomed -and upvoted- here. Meh.
