dynamiclly在javascript中構建對象鍵

Question

我有這種類型的數組：

var someArray = ['9213'，'9234'];

我要做到以下幾點有以下結果：

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

我怎樣才能做到這一點？是這樣的：

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

Answer 1

像這樣：

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. 
})
