componentDidSmoosh Code of Conduct

All guests, speakers, and volunteers at the componentDidSmoosh event are required to agree with the following code of conduct. Organizers will enforce this code throughout the event.

Because this is a comedy event, the tone and content of the presentations will differ from your usual tech event. Strong language, adult themes and dark humour may be presented. However, we the event organizers, are committed to providing a safe and inclusive space for our audience, and aim to create an environment of fun, love, kindness and respect for all our fellow human beings.

React SSR, SSG, SPA - History & Colour
