Cross-Browser JSON Parsing Issues in a React Application with Axios

I'm performance testing and I'm deploying to production and I just started working with I'm following best practices but I've searched everywhere and can't find a clear answer. Working on a project where our team is developing a React application that consumes a REST API returning JSON data. While the application functions well in Chrome, I've noticed discrepancies in how JSON data is parsed in Firefox and Safari. For instance, the API sends back a JSON object that contains a date in ISO format, which is handled correctly in Chrome but leads to unexpected behavior in other browsers. Here's a snippet of the response we're working with: ```json { "events": [ { "id": 1, "name": "Conference", "date": "2023-10-15T12:30:00Z" } ] } ``` In React, I'm using Axios to fetch the data: ```javascript import axios from 'axios'; const fetchEvents = async () => { try { const response = await axios.get('https://api.example.com/events'); const events = response.data.events.map(event => ({ ...event, formattedDate: new Date(event.date).toLocaleString() })); setEvents(events); } catch (error) { console.error('Error fetching events:', error); } }; ``` The `formattedDate` conversion works fine in Chrome but appears as `Invalid Date` in Firefox and Safari. I've tried different date formatting libraries like `date-fns` and `moment.js`, but the issue persists across browsers. I also ensured the API response headers are set correctly with `Content-Type: application/json`. In an attempt to debug, I logged the raw `event.date` value and found it to be intact in all browsers, so the discrepancy seems related to how `new Date()` handles the ISO string. Any suggestions on how to ensure consistent date parsing across different browsers? Should I consider a polyfill for better compatibility, or is there a recommended approach to handle this scenario more effectively? What's the best practice here? What are your experiences with this? Thanks in advance! For context: I'm using Javascript on Windows 10. I'd be grateful for any help. This is for a CLI tool running on macOS.
