Change detection in frontend frameworks (React, Vue, Angular, etc.)

[sonicoder86]

Description

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.

Takeaway

Change detection is often hard to grasp when something not happens when it is supposed to and these are hard to debug if we dont understanding the underlying fundamentals of immutability.
