indexOf off-by-one error
There is a slight error in the code that determines if a tweet contains the
word awesome. Specifically, on pages 219 and 221, the code that says
if (tweet.text.indexOf("awesome") >= -1) {
should not have the equals. In other words, it should read
if (tweet.text.indexOf("awesome") > -1) {
If indexOf returns -1, then it means it didn’t find the word. This is
actually correct in the code found in our Github repository.
This was caught by an incredibly sharp reader named Nick Litwin!
Thanks, Nick!
