将数组转换为具有默认值的对象的更简洁方法？ （洛达什可用）

我有一个数组，比如说["a","b","c"]，我想将其转换为一个对象，该对象以数组值作为键和我可以设置的默认值。所以如果默认值是true，我希望我的输出是{a:true, b:true, c:true}.

下面的代码是否有更简洁的版本来实现此目的？

var myObject = {};
["a","b","c"].forEach(x => myObject[x] = true);

我觉得有一种简洁的 Lodash 或 ES6 方法可以做到这一点，但我想不到。

标准配备Object.assign https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign and Array#map https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

var array = ["a", "b", "c"],
    object = Object.assign(...array.map(k => ({ [k]: true })));
    
console.log(object);

或者用 lodash 和_.set https://lodash.com/docs/#set

var array = ["a", "b", "c"],
    object = array.reduce((o, k) => _.set(o, k, true), {});

console.log(object);
