Using Google Chrome, there are few ways to stop JavaScript debugging.

Google Chrome 67 introduced some feature that lets to stop infinity loops without closing the current tab (source here).

Quick solution:

Pause and stop infinity loop in Google Chrome DevTools.
Pause and stop infinity loop in Google Chrome DevTools.

In the below sections, you will find more detailed descriptions with different approaches to stopping the infinite loops.

1. Stop button in Chrome DevTools example

Note: to use this approach, DevTools should be turned on before infinite JavaScript code will be executed. In other case, we will be not able to open the tools with F12 because of Google Chrome window freeze. It will be still possible to turn on the tools with browser menu, but tools will not get connection with executed source code to stop it - in this case code executing can be stopped only via closing tab or window. Sometimes for small amount of RAM or big amount of opened tabs DevTools can have problem to stop infinity script.

Steps:

  1. open Chrome DevTools with F12, Ctrl+Shift+i or from menu Main menu→More tools→Developer tools,
  2. open Sources tab,
  3. goto webpage that you want to debug,
  4. run some code that has infinity loop,
  5. click Chrome DevTools window to get focus on it,
  6. pause script with F8, Ctrl+\ or by clicking Pause script execution button (check 3rd step on the second screenshot),
  7. hold pressed mouse button for 1-3 seconds on the button again to see more options,
  8. move click action to square stop button on the expanded menu to stop permanently script execution.
