Swift Programming - Map Function

In this Swift programming tutorial, we will go over the map function.

Below are some code examples using map with an alternate closure syntax.

var a1 = [1, 2, 3, 4, 5]
var a1map = a1.map{x in x*2}
print(a1map)
// prints [2, 4, 6, 8, 10]

var a2 = ["green", "blue", "red"]
var a2map = a2.map{x in x.capitalized}
print(a2map)
// prints ["Green", "Blue", "Red"]

var a3 = ["a", "ab", "abc", "abcd", "abcde"]
var a3map = a3.map{x in x.count}
print(a3map)
// prints [1, 2, 3, 4, 5]

inline closure is weirdly satisfying to use. Something about utilizing the power of function in a syntax that doesn't look like it. BRILLIANT! Thanks a bunch for tutorials
