How to reproduce? Paste the code of the method in the console:

(Math.random().toString(36) + Date.now().toString(36)).substr(2, 10);

I tried to change toString to toISOString and it worked:

(Math.random().toString(36) + Date.now().toISOString()).substr(2, 10);

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React. Paste the link to your CodeSandbox (https://codesandbox.io/s/new) example below: I used code from https://fkhadra.github.io/react-toastify/the-gist-of-react-toastify What is the expected behavior? It should display the toast Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?
