How to extract a property from array of objects and slice it?

Question

so i have an array of objects which returns phoneNumber and businessNumber and name. I am trying to extract the businessNumber and phoneNumber and want to slice them from "-" to only show the last 4 digits?

I was able to use the map to extract the businessNumber but how can i split an return them both in the desired format?

myArray = [{
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
 {
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
 {
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
 {
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
]
let arr1 = myArray.map(function(obj) {
 return obj.businessNumber.split('-').pop()
})
console.log(arr1)

Thank you in advance.

• Finnnn: would you be able to provide an example of the output you want? It's not clear from the question. Thanks
• Somethingwhatever: @Finnnn please check the updated code, i made changes to the return line. but what would be the cleanest way of putting this on business and phone number together at the same time?

Answer 1

you could return both numbers in an array of new objects

let arr1 = myArray.map(function(obj) {
 return {
 businessNumber: obj.businessNumber.split('-').pop(),
 phoneNumber: obj.phoneNumber.split('-').pop() 
 }
})

Answer 2

You could do something like this if you change your map function slightly.

myArray = [{
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
 {
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
 {
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
 {
 phoneNumber: "[phone]",
 businessNumber: "[phone]",
 name: "Name1"
 },
]
let updatedArr = myArray.map((obj) => {
 obj.phoneNumber = obj.phoneNumber.split('-').pop()
 obj.businessNumber = obj.businessNumber.split('-').pop()
 return(obj);
})
console.log(updatedArr)
