JavaScript Tutorial: Merging Two Arrays while Maintaining Original Index Positions

I have two arrays that I need to merge together.

One array contains numbers, while the other array contains the corresponding titles for those numbers. This data was retrieved from a csv file, hence the current structure of the arrays.

Array 1: 

dataResults = [  0: "494,927", 1: "48,883", 2: "59,976", 3: "1,205,915"  ]

Array 2: 

dataTitles = [ 0: "News", 1, "Retail", 2: "Real Estate" 3. "Accounting" ]

I want to merge these two arrays into an array of objects, where index 0 contains both 429,927 and the title news.

Currently, I am populating these arrays by creating variables and adding data from the csv files.

const dataResults = []

const dataTitles = []

dataResults.push =(dataList[1][5], dataList[2][5], dataList[3][5], dataList[4][5])
 //console logs = 0: "494,927", 1: "48,883", 2: "59,976", 3: "1,205,915"

dataResults.push = (dataList[0][1], dataList[0][2], dataList[0][3], dataList[0][4])
// console log = 0: "News", 1, "Retail", 2: "Real Estate" 3. "Accounting"

What I've attempted is combining both pushes into one, but this creates additional indexed arrays. For example, 0: "News", 1: "494,927" instead of having them both as index 0.

My desired outcome is something similar to a JSON object: 

0 : [{ title: "News", result: "494,927 }]"
where I can access both results at index zero.

Answer №1

One way to achieve this is by utilizing the Array.prototype.map method:

const newData = dataTitles.map((title, index) => ({
    title,
    result: dataResults[index]
}));
