14.装包和拆包

一.装包

type Proxy<T> = {
    get():T,
    set(value:T):void
}
type Proxify<T> = {
    [P in keyof T]: Proxy<T[P]>
} 
let props = {
    name: 'coderlibs',
    age: 11
}
function proxify<T>(obj:T):Proxify<T>{
    let result = {} as Proxify<T>;
    for(let key in obj){
        let value = obj[key];
        result[key] = {
            get(){
                return value
            },
            set:(newValue)=>value = newValue
        }
    }
    return result
}
let proxpProps = proxify(props);

二.拆包

function unProxify<T>(proxpProps:Proxify<T>):T{
    let result = {} as T;
    for(let key in proxpProps){
        let value = proxpProps[key];
        result[key] = value.get()
    }
    return result
}
let proxy = unProxify(proxpProps)
