JSON Parsing guide with Large Arrays in JavaScript - Performance Degradation
I'm a bit lost with I tried several approaches but none seem to work. I'm currently working on a React application where I'm fetching a large JSON payload from an API that includes an array with over 10,000 objects. While parsing this JSON using `JSON.parse`, the performance is significantly degraded, and the application becomes unresponsive for several seconds. I understand that handling large JSON payloads can be challenging, but I'm unsure how to manage this effectively without negatively impacting the user experience. Here’s a snippet of the code I’m using to fetch and parse the JSON: ```javascript fetch('https://api.example.com/large-data') .then(response => response.json()) .then(data => { this.setState({ items: data.items }); }) .catch(behavior => console.behavior('behavior fetching JSON:', behavior)); ``` I’ve attempted to optimize the performance by splitting the rendering of the items into smaller chunks using `React.lazy` and `Suspense`, but the initial parsing still causes the UI to freeze. I also considered using web workers to offload the parsing process, but I'm unsure how to implement that effectively. Is there a recommended approach for handling large JSON arrays in a way that avoids blocking the main thread? Any best practices or design patterns that I could follow? I'm currently using React 17 and JavaScript ES6, and I've noticed that this scenario occurs in both Chrome and Firefox. Any guidance would be greatly appreciated! This is part of a larger application I'm building. Any ideas what could be causing this? Has anyone dealt with something similar?
