is there a betterway to merge json arrays into one

December 22, 2021

//working with vmware software
//so I can't use any JS library or python(i can but the method is harder there)
var env1ParsedScriptOutput='[{"somevalue":"stringified_jsonOuput1"},{"somevalue":"stringified_jsonOuput1"}]';
var env2ParsedScriptOutput='[{"somevalue":"stringified_jsonOuput2"},{"somevalue":"stringified_jsonOuput2"}]';
var env3ParsedScriptOutput='[{"somevalue":"stringified_jsonOuput3"},{"somevalue":"stringified_jsonOuput3"}]';

function rmvBrackets (){
  var newJson = [];
  for (var i=0; i<arguments.length; i++){
    var txt = arguments[i].replace(/(\[|\])/g,'');
    newJson.push(txt);
  }
  return newJson;
};
var allResults = rmvBrackets(env1ScriptOutput,env2ParsedScriptOutput,env3ParsedScriptOutput).toString();
var allScriptExecParsedOutput = '['+allResults+']'; //final return, this will be processed on another object

can anyone help me and enlightme. this is my code I’ve crafted with try and fail method.
I know there is must be a better way to do thisbut I just started to code with JS

>Solution :

I would concat it and apply Json.parse to turn it to an array.

Then use flat() to flatten it.

var env1ParsedScriptOutput =
    '[{"somevalue":"stringified_jsonOuput1"},{"somevalue":"stringified_jsonOuput1"}]';
var env2ParsedScriptOutput =
    '[{"somevalue":"stringified_jsonOuput2"},{"somevalue":"stringified_jsonOuput2"}]';
var env3ParsedScriptOutput =
    '[{"somevalue":"stringified_jsonOuput3"},{"somevalue":"stringified_jsonOuput3"}]';

const concat = `[${env1ParsedScriptOutput},${env2ParsedScriptOutput},${env3ParsedScriptOutput}]`;
const output = JSON.parse(concat).flat();

console.log(output);
