JavaScript & NodeJS Cambridge

Slides and recordings from our Meetup group

JavaScript & NodeJS Cambridge meetup group

Cambridge Intelligence proudly sponsors JavaScript & NodeJS Cambridge UK – one of the largest tech meetups in the city.


We’re a community of more than 1000 coders, dedicated to sharing knowledge and expertise. We meet every other month, either virtually or at a central venue (the drinks are on us 🍻 🍷 🍹) with speakers covering the entire JavaScript and NodeJS ecosystem.

We’re always looking for engaging and interesting contributors ready to share their experiences of the latest tools, frameworks and concepts. And new members are always guaranteed a warm welcome!

To join the group or sign up to the next meeting, visit the group’s meetup page.
