combine two array as key value pair - arrays

Question

I have two array as follows
var field_array=["booktitle","bookid","bookauthor"];
var data_array=["testtitle","testid","testauthor"];
I want to combine these two array and covert it to the following format
var data={
"booktitle":"testtitle",
"bookid":"testid",
"bookauthor":"testauthor"
}
I want to insert this data to database using nodejs
var lastquery= connection.query('INSERT INTO book_tbl SET ?',data, function (error, results, fields) {
if (error) {
res.redirect('/list');
}else{
res.redirect('/list');
}
});
Please help me to solve this.

Answer 1

var field_array = ["booktitle", "bookid", "bookauthor"];
var data_array = ["testtitle", "testid", "testauthor"];
var finalObj = {};
field_array.forEach(function (eachItem, i) {
finalObj[eachItem] = data_array[i];
});
console.log(finalObj); //finalObj contains ur data

Answer 2

You also can use reduce() in a similar way:
var field_array=["booktitle","bookid","bookauthor"];
var data_array=["testtitle","testid","testauthor"];
var result = field_array.reduce((acc, item, i) => {
acc[item] = data_array[i];
return acc;
}, {});
console.log(result);

Answer 3

Here I explaned my code line by line..Hope it will help
var field_array = ["booktitle", "bookid", "bookauthor"];
var data_array = ["testtitle", "testid", "testauthor"];
//Convert above two array into JSON Obj
var jsondata = {};
field_array.forEach(function (eachItem, i) {
jsondata[eachItem] = data_array[i];
});
//End
//Store Jsondata into an array according to Database column structure
var values = [];
for (var i = 0; i < jsondata.length; i++)
values.push([jsondata[i].booktitle, jsondata[i].bookid, jsondata[i].bookauthor]);
//END
//Bulk insert using nested array [ [a,b],[c,d] ] will be flattened to (a,b),(c,d)
connection.query('INSERT INTO book_tbl (booktitle, bookid, bookauthor) VALUES ?', [values], function(err, result) {
if (err) {
res.send('Error');
}
else {
res.send('Success');
}
//END
