Question

What is the process for transforming an array into an array object using javascript?

Here is a situation where I need to upload a text file that contains data in the following format:

a1,b1,,c1,d1,
a2,b2,,c2,d2,

After reading and splitting the data with ("\n"), it results in an array like this:

array=[array[0]:[a1,b1,,c1,d1]
       array[1]:[a2,b2,,c2,d2]]

I am looking for a way to populate the above array into my array object.

For example, the desired output would be:

newarray=[[name="a1",age:"b2",address="",contact="c1",gender="d1"],
           [name="a2",age:"b2",address="",contact="c2",gender="d2"]]

Answer №1

One approach to tackle the fixed position of attributes in an array is to create a function that assigns values based on their predetermined positions. Here's an example:

var data = "John,30,123 Main St.,123-456-7890,Male\nJane,25,456 Park Ave.,987-654-3210,Female";
var records = parseData(data);
console.log(records);

function parseData(dataString){
  var recordList = [];
  var lines = dataString.split("\n");
  for(var i=0;i<lines.length;i++){
    var valueArray = lines[i].split(",");
    recordList.push(mapToRecord(valueArray));
  }
  return recordList;
}

function mapToRecord(array){
  return {
    name: array[0],
    age:array[1],
    address: array[2],
    contact: array[3],
    gender:array[4]
  };
}
