mapping - Javascript - Converting string to number in an array of objects

Question

I have an array of objects called reports that has an object reportId that is currently returning as a string. I would like to convert that object reportId to integers. How can I do this with an array of objects?

I've attempted to accomplish this with mapping. and using parseInt but I am not having success.

Here is an example of my code:

let reports = [ {reportId: "21", title: "Online", code: "ON" }, {reportId: "11", title: "Retail", code: "RE" }, {reportId: "61", title: "Walk-in", code: "WI" } ]



 let ids = reports.reportId.split(',').map(function (item) {
        return parseInt(item, 10);
    });
    
console.log(ids)

Answer 1

You are over-complicating things; you just need to map each entry in reports to its reportId property and convert that to an integer

let reports = [ 
  {reportId: "21", title: "Online", code: "ON" },
  {reportId: "11", title: "Retail", code: "RE" },
  {reportId: "61", title: "Walk-in", code: "WI" } 
]

let ids = reports.map(function (item) {
  return parseInt(item.reportId, 10);
});
    
console.log(ids)
