JavaScript variable assignments from tuples

Question

Javascript 1.7 added destructuring assignment which allows you to do essentially what you are after.

function getTuple(){
   return ["Bob", 24];
}
var [a, b] = getTuple();
// a === "bob" , b === 24 are both true

You have to do it the ugly way. If you really want something like this, you can check out CoffeeScript, which has that and a whole lot of other features that make it look more like python (sorry for making it sound like an advertisement, but I really like it.)

You can do something similar:

var tuple = Object.freeze({ name:'Bob', age:14 })

and then refer to name and age as attributes

tuple.name 
tuple.age 

This "tuple" feature it is called destructuring in EcmaScript2015 and is soon to be supported by up to date browsers. For the time being, only Firefox and Chrome support it.

But hey, you can use a transpiler.

The code would look as nice as python:

let tuple = ["Bob", 24]
let [name, age] = tuple

console.log(name)
console.log(age)
