Sorting by alphabetical order immutable.js
提问by lipenco
I would like to sort immutable.js orderedList by property name,
我想按属性对 immutable.jsorderedList 进行排序name，
data.map(x => x.get("name"))returns the string, I want to sort my map by name in alphabetical order.
data.map(x => x.get("name"))返回字符串，我想按字母顺序按名称对我的地图进行排序。
How to do that? I tried:
怎么做？我试过：
return data.sortBy((val) => {
if (dir === "up") {
return val.get("name");
} else {
return - val.get("name");
}
});

var fiends = Immutable.fromJS([{name: 'Squirrel'}, {name: 'Cat'}, {name: 'Raccoon'}]);
var sorted = fiends.sortBy(
(f) => f.get('name')
);
sorted.map(x => x.get('name')).toJS(); // ["Cat", "Raccoon", "Squirrel"]
With localCompare:
使用localCompare：
fiends.sort(
(a, b) => a.get('name').localeCompare(b.get('name'))
);
