Open newPromise opened 5 years ago

newPromise commented 5 years ago 
@params { Array } deleteIndexs 需要进行删除的数组所有索引值
@params { Array } deleteArrs 需要进行删除的数组
const deleteArray = (deleteIndexs, deleteArrs) => deleteIndexs.forEach((val, index, arr) => deleteArrs.splice(val - index, 1));

test:

const arr = [1, 2, 3, 4, 5];
const indexs = [2, 3];
deleteArray(indexs, arr); // [1, 2, 5]
