在javascript中动态构建对象键

Question

我有这种阵列：

var someArray = ['9213'，'9234'];

我想做以下结果有以下结果：

var obj = {
   9213:true,
   9234:true
}

我怎样才能做到这一点？类似的东西：

obj = [];
_.each(someArray, function(currentNum,i){
     obj.push(); //here i should do something 
})

Answer 1

像这样：

obj = {}; // {} means object and [] means array
_.each(someArray, function(currentNum,i){
     obj[ currentNum ] = true;
     //by using [ currentNum ] you will create object property name as "9213" for example.
})
