Questions & Answers

Q: What are the three main threads in the current React Native architecture?

The three main threads are JS Bundle, Native UI, and Shadow Tree. JS Bundle handles React Native code, Native UI manages interactions, and Shadow Thread calculates layout dimensions.

Q: How does JSI (JavaScript Interface) improve React Native performance?

JSI, written in C++, removes the need for JSON serialization/deserialization, leading to faster performance and increased flexibility in React Native apps by directly accessing native elements.

Q: What is Fabric in React Native, and how does it tackle performance issues?

Fabric is a new rendering approach in React Native that prioritizes tasks like tapping and scrolling to enhance UI performance and avoid frame drops commonly seen in elements like flat lists.

Q: What concerns exist with the introduction of JSI in React Native?

There are concerns regarding the dynamic typing of JavaScript in JSI and the potential need to shift towards TypeScript or use code generation tools to ensure type safety in React Native development.
