Topics for our December edition:

🎭 Playwright - one of the few things Microsoft did right
by Márk Fejes - JavaScript Tech Lead at Supercharge

Although traditional E2E testing stacks, like Selenium serve well, why stick to old ways if we can take automatic testing to the next level? Playwright, an open-source and totally free framework enables end-to-end testing for modern web applications and offers all the reliability and performance I missed up until now!

In my presentation, I’ll showcase through live examples what I’ve learned while exploring the tools offered by Playwright and compare them with other traditional testing stacks.

🔄 Change detection in frontend frameworks
by Gábor Soós - Emarsys

Displayed data within applications often change dynamically and this change needs to be reflected to the end user. What happens if the remote request completes, we update the stored data but on the UI nothing changes but it should? How does a framework detect if your data has changed? How can we detect different data points in Javascript?

In this talk I'll show with Javascript operators and features how can we detect if one set of data is different from another one and how do these are implemented in the biggest frameworks. The talk is targeted mainly on the existing Javascript features and not the quirks of each framework.
