什么是这个php json_encode的Node.js等价物？

Question

I am looking for the Node.js of the following PHP Script:

$SMA_APICall = "https://www.alphavantage.co/query?function=SMA&symbol=".$symbolValue."&interval=15min&time_period=10&series_type=close&apikey=R3MGTYHWHQ2LXMRS";
          $SMAresponse = file_get_contents($SMA_APICall);
          $jsonSMA = json_encode( $SMAresponse);

Here, I am trying to make a call to an API. The API call returns a json object. I want to repeat the same thing using Node js

Take a look at the request library: https://github.com/request/request

var request = require('request');
var url = "https://www.alphavantage.co/query?function=SMA&symbol=" + symbolValue + "&interval=15min&time_period=10&series_type=close&apikey=R3MGTYHWHQ2LXMRS";
request(url, function (error, response, body) {
  if (!error && response.statusCode == 200) {
    var jsonSMA = JSON.parse(body);
    // Continue code here
  }
});
