There is a spelling error on the following page:
https://learn.freecodecamp.org/javascript-algorithms-and-data-structures/debugging/use-typeof-to-check-the-type-of-a-variable

The following sentence:
Especially take care when you're accessing and working with external data in the form of a JavaScript object (JSON).

Should read:
Especially take care when you're accessing and working with external data in the form of a JavaScript Object Notation (JSON).

I would love to fix this on my own if someone could tell me how....
