conversion of 2d array to json object in javascript

Question

consider my array in nodejs as

[x:["xyz","abc","uvw","efg"],y:["wer","mno","sdk"]]

when i tried converting this array using JSON.stringify() i could get only [] in return.

is there any way to store multiple values like array in Object data type.

Answer 1

You can't use array with a non-numeric index. In your case you should use an object instead: {x:["xyz","abc","uvw","efg"],y:["wer","mno","sdk"]} .

Be aware that you can get keys of this object with Object.keys(obj) . It returns an array ['x', 'y'] and you can iterate through the object.
