sending an array of data through postman to node

Ok I want to send an array of data and fetch it based on its index. 

rate = [10,20,30,40,50,60,70,80,90,100,110,120,200];

enter image description here

when I try

console.log(req.body.rate); // output : [10,20,30,40,50,60,70,80,90,100,110,120,200]
console.log(req.body.rate[2]) // gives 0 
 // Also tried
var array = [];
array = req.body.rate;
console.log(array[2]) // same as above

I know I can loop and push etc. But I don't want to loop. Can anyone help me where I am gooing wrong.

Could you send an array of objects instead? Then you could do something like this: 

var arr = [
    {
        "key": "value" 
    },
    {
        "key": "value1" 
    },
    {
        "key": "value2" 
    }
]

console.log(arr[1].key)

It seems that in your case req.body.rate it returns a string not an array.

To obtain an array, use split method.

var array = [];
array = req.body.rate.split(',');
console.log(array[2])
