Inconsistent Function Names in Ch 4 and Ch 5

[semmypurewal]

From Mike Hennessey:

Typo in the print version:

Ch. 5, p. 179 reads:
"remember that I had you write a function called containsNTimes"

The above sentence is a reference to Ch. 4, p. 146, which reads:

"Write a function that accepts three arguments and returns true if the
array contains the element n times, where n is the third argument:"

"arrayContainsNTimes(["a","b","a","c","a"], "a", 3);"

So the function name has to be changed in one place or the other, to be consistent.
