Machine freezing while developing react app

last week my machine start hanging while I'm developing react app.

Machine specifications

Alt Text

I thought this happening because :-

1) I'm using PHPSTORM (for the back end) and webstorm (for frontend) so I restarted my machine and didn't open any of those IDEs and started the application via chrome / Firefox but also freezed.

2) My coworker asked me to install https://www.npmjs.com/package/gtop and check the processes, also we checked the pc cooling system but also freezed.

3) I disabled all chrome extensions using this extension https://chrome.google.com/webstore/detail/disable-extensions-tempor/lcfdefmogcogicollfebhgjiiakbjdje but also freezed.

Today (first work day)
3) I write down this script https://gist.github.com/MoatazAbdAlmageed/10af8fb6e587dcd9b2039fd8f4ff1c85 to kill chrome if available memory less than 1GB and when I start developing I found chrome hanging and closed when I pressed a button

Finally I noticed that I typed bad reducer behavior that made like an infinity loop :) that's it

I think this can help in cases like this https://github.com/facebook/react/issues/5375
