What is the difference between these Arrays?

var xyz = ["x","y","z"]

var xyz = ["x"],["y"],["z"]

getting_started.swift 
let bestSmartphone = "iPhone"
var favoriteSports: [String] = ["football"], ["basketball"], ["tennis"]

let bestSmartphone = "iPhone"
var favoriteSports: [String] = ["football"], ["basketball"], ["tennis"]

The second line gives a compilation error, the array of strings is not declared correctly 

var favoriteSports: [String] = ["football",  "basketball", "tennis"]

Individual items within the array must be separated by commas

So this example Array

var xyz = ["x"],["y"],["z"]

Is incorrect? All the items must be inside the bracket?
