回答by Suren Srapyan
Just pass a function to the sort, based on which you want to sort the array
只需将一个函数传递给排序，根据您要对数组进行排序
.sort((a,b) => b - a)

Your code
你的代码
this.display=this.addition.sort();
will sort the array in ascending order, to sort in descending order you need to pass a comparator function.
将按升序对数组进行排序，要按降序排序，您需要传递一个比较器函数。
this.display=this.addition.sort((a,b) => b - a);
