How to sort object array based on key in typescript
提问by Manohar
I have a candidate object with properties
我有一个具有属性的候选对象
candidateid:number;
name:string;
I wish to sort an array of such objects based on the nameproperty. How can I achieve this in TypeScript in angular 2?
我希望根据name属性对此类对象的数组进行排序。如何在 angular 2 的 TypeScript 中实现这一点？

It's the same as plain old javascript. You can still use an arrow function to make it more concise.
它与普通的旧 javascript 相同。您仍然可以使用箭头函数使其更简洁。
x.sort((a, b) => a.name < b.name ? -1 : a.name > b.name ? 1 : 0)
Or using localeCompare.
或者使用localeCompare。
x.sort((a, b) => a.name.localeCompare(b.name))
