通过数组的键将数组转换为对象

Question

What is the best way to convert:

Dynamically I am getting an array.

For example we can consider this following array.

[
    'typeRead_1',
    'typeModify_1',
    'typeModify_2',
    'typeRead_3',
];

But I want it something like this. to:

{
    1: {
      typeRead: true,
      typeModify: true,
    },
    2: {
      typeRead: false,
      typeModify: true,
    },
    3: {
      typeRead: true,
      typeModify: false,
    }
  };

Here is one way of doing this:

 const items = [ 'typeRead_1', 'typeModify_1', 'typeModify_2', 'typeRead_3', ]; const ret = items.reduce((ret, el) => { let [prop, key] = el.split('_'); if (!ret[key]) ret[key] = { typeRead: false, typeModify: false }; ret[key][prop] = true; return ret; }, {}) console.log(ret)
