Arrays Length
The length property
Maybe the most commonly used property when working with arrays, is the length property. The length property of an array is used to reveal how many elements the checked array possesses.
Thus you can compare later if an array has more elements than another one etc.
The value that is given back is a number (integer). In this case the belovedLanguages' length is 4, while hatedLanguages' length is 7.
