The JSON object that is printed out by the console looks something like this (formatted for easier reading):

{
  "coord":{"lon":-97.74,"lat":30.27},
  "weather":[
    {"id":800,"main":"Clear","description":"clear sky",
       "icon":"01n"}
  ],
  "base":"stations",
  "main":{
    "temp":305.59,
    "pressure":1016,
    "humidity":46,
    "temp_min":304.15,
    "temp_max":307.15
  },
  "visibility":16093,
  "wind":{
    "speed":3.6,
    "deg":170,
    "gust":8.2
  },
  "clouds":{"all":1},
  "dt":1534470960,
  "sys":{
    "type":1,
    "id":2558,
    "message":0.0037,
    "country":"US",
    "sunrise":1534507156,
    "sunset":1534554612
  },
  "id":4671654,
  "name":"Austin",
  "cod":200
} 

That's a lot of weather data! Luckily, because the request npm module was passed the json: true property in the options, it assumes that anything passed back is JSON and parses it for you, so you can access data properties right away:

let longitude = body.coords.lon // -97.74
let conditions = weather.condition // 'clear sky'
let currentTemp = main.temp // 305.59 degrees Kelvin
