Ways to extract information from a text

I have a massive string, divided into two parts that follow this pattern: 

     {\"Query\":\"blabla"\",\"Subject\":\"gagaga"}",   
     {\"Query\":\"lalala"\",\"Subject\":\"rarara\"}",

and so on... (thousands of lines)

My goal is to create a variable that contains these values:

data= "blabla,gagaga","lalala,rarara",....

This is the code I'm using but it's not functioning correctly:

var contentss = JSON.stringify(allFileGenesDetails1);
data="";
var Query1="";
var Subject1="";
// Parse the data

var contentEachLines = contentss.split("\n");
for (var jj = 0; jj < contentEachLines.length; jj++) {
var lineContent = contentEachLines[jj].split("\t");

var divided = lineContent[jj].split(",");
Query1= Query1+ [divided[0]];
Query1 = Query1.replace(/Query|:|{|"|\|/gi, "");

Subject1=Subject1+ divided[1];
Subject1 = Subject1.replace(/Subject|:|{|"|\|/gi, "");
data=data+"'"+ Query1+","+Subject1 +" ' " +"," ;
javascriptstring

Answer №1

Give this a try:

let fileGenes = JSON.parse("[{\"Query\":\"blabla\",\"Subject\":\"gagaga\"},{\"Query\":\"lalala\",\"Subject\":\"rarara\"}]");
let output = "";
for(let i = 0; i < fileGenes.length; i++) {
    if((i+1)==fileGenes.length)
        output += fileGenes[i].Query+","+fileGenes[i].Subject;
    else
        output += fileGenes[i].Query+","+fileGenes[i].Subject+",";
}
console.log(output);
