How to check for errors on the browser console?
Hotkey for launching Chrome DevTools:
- Windows: F12 or CTRL + Shift + I
- macOS : Cmd + Opt + I
You can also open Chrome DevTools from the tools menu in your browser:
Make sure you are on the " Console" tab and note that we are only looking for errors. Select the "error" category from the left-side panel to filter other not-so-important warnings and notices.
This process is similar for the Firefox browser.
