It additionally does now not require you to be told any new APIs to make use of. “We’ve heard your comments. There’s recently too many runtimes, configuration choices, and rendering easy methods to must imagine. You need the velocity and reliability of static, whilst additionally supporting totally dynamic, customized responses. Having nice efficiency globally and personalization shouldn’t come at the price of complexity,” Lee Robinson, VP of developer revel in at Vercel, and Tim Neutkens, engineering supervisor for Subsequent.js, wrote in a blog post.
