javascript - Obtaining a value from an object consisting of Array

I have an object including only one Array(17). I would like to get from this array specific value, ex for index = 4 -> 1523181939.

How can I get it?

I am getting a console result by running:

this.temp = this.flights['states'];
console.log(this.temp);
console.log(typeof this.temp);

My object this.flights is of the form

{time: 1523183848, states: Array(1)}
states: [Array(17)]
time: 1523183848 
__proto__: Object

When I call this.flights['states'] I get:

[Array(17)]

Lastly when calling this.flights['states'][0][4] I get an error:

ERROR TypeError: Cannot read property '0' of undefined

Starting flights object I am getting from Opensky-Network Api:

{
    "time": 1523183840,

    "states": [
        [
            "89906e",
            "EVA857  ",
            "Taiwan",
            1523183838,
            1523183839,
            121.2966,
            25.1178,
            716.28,

            false,
            111.38,
            50.06,
            8.78,
            null,
            746.76,
            null,
            false,
            0
        ]

    ]
}

Answer

Working code is below.

Access your element of array on an object like this this.temp = this.flights.states[0][4];

Do it like below:

var flights = {"time":1523183840,"states":[["89906e","EVA857  ","Taiwan",1523183838,1523183839,121.2966,25.1178,716.28,false,111.38,50.06,8.78,null,746.76,null,false,0]]};



this.temp = this.flights.states[0][4];
console.log(this.temp);
console.log(typeof this.temp);
