在 typescript 中将 2 个不同类型的 object arrays 分配给彼此的最佳方法是什么？

Question

I want to assign 2 different type array to eachother attribute by attribute. Can someone explain me what is the best way for this purpose? I am using the code below, but when I have too much attribute, it does not good look. How can I map attributes easily?

    export interface ClassA {
        Type: string;
        Name: string;
    }

    export interface ClassB {
        Typ: string; 
        Nm: string; 
    }



    let  items: ClassA[] = [
    { Type: 'T1', Name: 'N1'},
    { Type: 'T2', Name: 'N2'},
    { Type: 'T3', Name: 'N3'},
    ];

     
    let  items2:ClassB [] = [];


   items.forEach((item, index) => {
            let obj: ClassB  = {Typ:item.Type, Nm:item.Name };
            items2.push(obj);          
        });

console.log(items2);

Use map instead since you can map from one type to another type with it. With explicit type annotations, it also gives you inference and typechecking in the map predicate as well:

let items2: ClassB[] = items.map((item) => ({ Typ: item.Type, Nm: item.Name }));
