export abstract class XXXX<T = void> {
    protected progressDetail: Record<string, number> = {};
    protected progressMessage: Record<string, string> | string = '';
    protected progressWeight: Record<string, number> = {};

    protected get progress(): ProgressArgs {
        const { progressDetail: detail, progressMessage: msg, progressWeight: weight } = this;  // 这句不太明白是什么语法或者语言特性

        // 后续代码可直接访问detail,msg,weight等变量
        // 似乎detail等价于this.progressDetail
        

        }

}



请问这种写法：
const { progressDetail: detail, progressMessage: msg, progressWeight: weight } = this;
是JavaScript（或TypeScript）中的什么语言特性或者语法糖？有无MDN的文档介绍？
