how to prevent possible javascript memory hogging from crashing a browser

问题

Especially when using while loops scenarios can arise where javascript gets stuck in a continuous loop that can crash the browser.

I usually handle this possibility by using a variable to count the number of while executions and break the while after a certain time.

While the browser no longer crashes it can still slow things down considerably.

Is there a more efficient way of handling this possibility?
