Not sure why this was downvoted. The click-baity "Yes, JSON" is really annoying and should be removed. More generally, the title should be corrected to the actual title, which is almost fine: "How to build cross-platform mobile apps using nothing more than a JSON markup" Maybe remove the click-baity "nothing more than" part, but other than that, the original title is much better than the submission title.
