Marko.js: Unsung Hero of Scalable Web Frameworks

Marko.js is a JavaScript framework created by eBay back in 2014. It offers super-efficient server-side rendering, making it ideal for big e-commerce sites and other multi-page apps where speed and SEO really matter. After over 10 years of development, Marko has some standout features that make it an interesting choice. In this talk, I’ll dive into these unique features and showcase some of Marko's innovative solutions. You might not use Marko.js at your company, but there’s still a lot you can learn from it to bring to your next project.
