console.log(0.1 + 0.2);
console.log(0.4 + 0.1 == 0.5);

This is a trick question in that at first glance, you might expect the console to print out “0.3” and “true.” The correct answer is that you can't know for sure, because of how JavaScript treats floating point values. In fact, in the above example, it will print out:

0.30000000000000004
false
