Change array to object using javascript

Question

I need to change an array into an object using javascript

For an example. I have an array which looks like :

colours [        
["black","red",shades : ["0","1","2"]]        
]

I want to change this to :

colours [
    {
    "black","red", shades : ["0","1","2"]
    }
]

Can anyone please tell me how I can do this using javascript code.

["black","red",shades:["0","1","2"]] this is not a valid array. arrays dont have defined keys in js, only object — VMcreator, Aug 07 '15 at 02:19
Check out [what an object looks like](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object) and [what an array looks like](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array?redirectlocale=en-US&redirectslug=JavaScript%2FReference%2FGlobal_Objects%2FArray), and tell us why you want to do this. — iplus26, Aug 07 '15 at 02:27
i am sorry for the confusion. I am a beginner. What i want to do it to make JSON object. colours [ { "black","red", shades : ["0","1","2"] } ] will that be correct? — qualitytest, Aug 07 '15 at 02:29
No, I'm afraid that will not be correct. You need to post what you actually have. You don't have the things you posted because they cannot exist. — david, Aug 07 '15 at 02:32
I am afraid it is difficult to share entire code. I can show the browser debug content. what i have currently is this 0: Array[0] prop1: Object prop2: Array[40] descriptor: Array[0] prop3: Array[10] prop4: Array[1] __proto__: Array[0] length: 1 __proto__: Array[0] what i want to change to is this 0: Object prop1: Object prop2: Array[40] descriptor: Array[0] prop3: Array[10] prop4: Array[1] __proto__: Array[0] length: 1 __proto__: Array[0] — qualitytest, Aug 07 '15 at 02:40
Why don't express your object as `{colors: ["black","red"], shades:["0","1","2"]}` ? Your sample object notation doesn't make sense at all. — TaoPR, Aug 07 '15 at 03:24
