javascript - 将对象转换为 typescript 中的模型

Question

我在下面的示例中有一个类似 lst 的 json，我想将它映射到 MyModel。

interface MyModel { 
    id: number;
    isRequired : boolean;
    ,...
}

let lstByModel: Array<MyModel> = [];

// lst comes from API
let lst:any[] = [
    {
        "id":"10",
        "isRequired":"false"        
    }
];

lstByModel = lst; // How to map lst to MyModel (lstByModel)?

console.log(lstByModel); // it shows { id : "10" , isRequired : "false"} but I need { id : 10, isRequired : false } How can I do that?

提前致谢。

您可以使用 Object.assign()

The Object.assign() method is used to copy the values of all enumerable own properties from one or more source objects to a target object. It will return the target object.
