webology, 
👋 Hi, friends who have landed on Eleventy, preferably from Jekyll.
Are there any growing pains and positive stories you can share?
Is moving from Jekyll templates to Eleventy an apples-to-apples experience, or are they different enough to be a total rewrite?
Also, will an Eleventy created today still work in two, three, or five years, or is keeping up with npm/JS an issue?
