// An example of the stripTags() method
// You can see that it removes all the HTML from the string
// and leaves us with a clean text-only string
"<b><i>Hello</i>, world!".stripTags() == "Hello, world!"

// An example of toArray() method
// We get the fourth character in the string
"abcdefg".toArray()[3] == "d"

// An example of the camelize() method
// It converts the old string to the new format.
"background-color".camelize() == "backgroundColor"
