In this exercise, we count how many times the letter ‘p’ occurs in Peter Piper’s famous tongue twister:
Peter Piper picked a peck of pickled peppers.
A peck of pickled peppers Peter Piper picked.
If Peter Piper picked a peck of pickled peppers,
Where's the peck of pickled peppers Peter Piper picked?
Update file peter-piper.js, adding the correct code to
count the number of times a “P” occurs in the Peter Piper tongue twister. Be
sure to count both uppercase P and lowercase p characters.

completed your solution. You can ask questions or request feedback there in your
pull request. Just mention @barberboy in your comments to get my attention.
Want to work a bit harder? Try these variations:
-
Define a function called
countOccurrences(string, char), which counts the number of times the charactercharoccurs in the stringstring, then call it to find the number ofp's in the tongue twister, like:
var counter = countOccurances(peterpiper, 'p');. -
Instead of looking for the letter 'p', count the number of times the word
'peck'occurs in the tongue twister. -
Try counting the occurrences of
'p'without using aforloop. Take a look at the other String.prototype methods for ideas.
