I think it's ubiquitousness, not developer experience, but perhaps that's what you meant. Both PHP and Javascript are examples of that. PHP wasn't nicer to use than other languages, it was just available to everyone. They're also both unencumbered by the aspirations of software engineering. The language doesn't care that you're writing untyped, procedural spaghetti code, they're very forgiving and so are the community and ecosystem.
