Too Long; Didn't Read

Arrays in Javascript are a simple, one-dimensional way to store simple sets of data. Arrays are non-unique, which means they can store duplicates (unlike sets).

That just means that all arrays inherit a certain set of specific methods, like length, some(), every(), concat(), any many more.
