I have ran into a problem, the error is
regeneratorRuntime is not defined while working with React and Parcel bundler.
The problem appeared after I added an async function and while searching the problem, I found a stack-overflow solution but it didn't work. So, don't use this method.
First, I found this solution:
import "babel-polyfill";at the top of the file that you are using the async function.
later learned that babel-polyfill is deprecated. So, to solve the regeneratorRuntime problem, do this:
npm install --save regenerator-runtime
Update webpack file
entry: ["regenerator-runtime/runtime.js", "<your enter js file>"]
import 'regenerator-runtime/runtime'at the top of the file that you're using async function
I didn't edit webpack, because I'm using Parcel, but just importing regenerator-runtime/runtime at the top of the file solved the problem.
