Hi, I'm Chris Ferdinandi. 👋

Chris Ferdinandi

I help people learn vanilla JavaScript, and I believe there’s a simpler, more resilient way to make things for the web.

I’ve taught developers at organizations like Salesforce and the Boston Globe, and my JavaScript libraries have been used by organizations like Apple and Harvard Business School. My developer tips newsletter is read by over 14k developers each weekday.

I want to help you master vanilla JavaScript, without all of the painful false starts and roadblocks I encountered when I was learning.

Clarity. Brevity. Unpretentious explanation. Care for best practices. Obvious attentiveness. Available to help "unstuck" students. You actually rock, Chris.- Kabolobari Benakole
We need more people like Chris, who not only have this mindset that we need to stick to the basics of JavaScript, but are willing to evangelize it.- David Walsh
