Passing JavaScript Developer I and what I learned along the way

The JavaScript Developer I Certification is new in more than one way: It is the first JavaScript Certification but also the first exam that exclusively deals with off-platform technology – ES6, node and npm. This session will showcase an two-part app that I built using node, npm, LWC OSS and heroku to cover exam preparation . I think, it will come in handy at your next community session, too
