// An example race condition in JavaScript
// When you run this script using Node or in a browser, you'll find 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 https://en.wikipedia.org/wiki/Time-of-check_to_time-of-use

let number = 0;
const times = 100;
