An example race condition in JavaScript
When you run this script using Node or in a browser, it
does not print “Ended with 0”, but a random number.
Even though the functions running
simply loop 100 iterations of adding and subtracting.
The reason the end result is random is because the
sleeps are of random duration and the time between the read
of the variable causes the eventual write to be incorrect
when adder and subber interleave.
This problem is similar to:
