The “new” Swift programming language from Apple is nothing more that syntactic sugar on top of Javascript.
A few examples from Swift Welcome page and Swift Tour page
Example 1:
Swift code:
============================
let people = ["Anna": 67, "Beto": 8, "Jack": 33, "Sam": 25]
for (name, age) in people {
println("\(name) is \(age) years old.")
}
==============================
JS code ( http://jsfiddle.net/SSD9Y/1/ ) :
============================
var people = {"Anna": 67, "Beto": 8, "Jack": 33, "Sam": 25}
for ( person in people ) {
alert( person + " is " + people[person] + " years old.")
==============================
Example 2:
Swift code:
============================
let cities = ["London", "San Francisco", "Tokyo", "Barcelona", "Sydney"]
let sortedCities = sort(cities) { $0 < $1 }
if let indexOfLondon = find(sortedCities, "London") {
println("London is city number \(indexOfLondon + 1) in the list")
}
==============================
JS code ( http://jsfiddle.net/pYWb9/1/ ) :
============================
var cities = ["London", "San Francisco", "Tokyo", "Barcelona", "Sydney"]
var sortedCities = cities.sort()
indexOfLondon = sortedCities.indexOf("London")+1
alert("London is city number " + indexOfLondon + " in the list")
==============================
Example 3:
Swift code:
============================
var shoppingList = ["catfish", "water", "tulips", "blue paint"]
shoppingList[1] = "bottle of water"
var occupations = [
"Malcolm": "Captain",
"Kaylee": "Mechanic",
]
occupations["Jayne"] = "Public Relations"
==============================
JS code ( http://jsfiddle.net/p3FM6/1/ ):
============================
var shoppingList = ["catfish", "water", "tulips", "blue paint"]
shoppingList[1] = "bottle of water"
var occupations= {Malcolm: 'Captain',Kaylee:'Mechanic'}
occupations["Jayne"] = "Public Relations"
==============================
Example 4:
Swift code:
============================
let individualScores = [75, 43, 103, 87, 12]
var teamScore = 0
for score in individualScores {
if score > 50 {
teamScore += 3
} else {
teamScore += 1
}
}
teamScore
==============================
JS code ( http://jsfiddle.net/s9DF5/1/ ):
============================
var individualScores = [75, 43, 103, 87, 12]
var teamScore = 0
for (score in individualScores) {
if (score > 50) {
teamScore += 3
} else {
teamScore += 1
}
==============================
Longe de mim ser defensor da PT (aka Altice). Pela opinião expressa no artigo atrás (e verbalmente em alguns eventos públicos), fui banido de ser convidado para eventos patrocinados pela PT. Em 97 chateou-me ser arguido em processo crime (com potencial pena de prisão de 3 anos) por causa das práticas anticoncorrênciais dessa organização mafiosa. E nem hoje em dia tenho grande simpatia pela mesma, uma vez que não tenho as melhores memórias de interagir com o seu falso e hipócrita CEO quando trabalhava na Oni (o homem que em 2000 recusou uma proposta minha para criar o YouTube; Altice Labs Inovação my ass…).
