Underscore で 2つの配列の内容が同一化どうかをしらべる

More than 5 years have passed since last update.

目的

Underscore.js を使って、2つの配列が順番に限らず同一かを比較したい。

たとえば、

x = [1, 2, 5, 3]
y = [1, 3, 2, 5]
comp(x,y) = true
x = [1, 2, 5, 3]
y = [1, 3, 2, 4]
comp(x, y) = false
x = [1, 2, 5, 3]
y = [1, 3, 2]
comp(x, y) = false

こうやる

function comp(x, y){
    return _.all(_.map(_.zip(x.sort(), y.sort()), function(pair){return pair[0] === pair[1];}));
}
