Javascript-101/testing-type: format type correctly

[arthurvr]

Three little corrections to the formatting of a a type in javascript-101/testing-type:

• The type itself must not have a capital O. It's not a constructor.

> typeof []
'object'

• It's 'code', so it must be wrapped within backticks.
• The dot ending the sentence must be outside of the backticks.

Since object is enclosed in back-ticks, you're right that the period should appear outside the quotation mark. However, if the word remained in quotation marks, then it would be correct (in American English, which is what we use for jQuery's documentation) to keep the period inside the ending quotation mark.

I hope I'm not coming off as pedantic. I just wanted to note it here in case you come across similar uses of quotation marks in the future.

True. Was a miswording of mine.
