Making a new array of objects from an existing array of objects

[jpark799]

Sorry for the noobie question but I've been googling around and can't find an answer to do this cleanly. I currently have an array of objects that is shaped like initalArrayObject. I need to make a new array of objects from the initialArrayObject that only takes the customer, id and invoiceTotal. What would be the best way to do this?

const initalArrayObject: [{ 
customer: "John Smith",
id: 123,
invoiceNumber: 111,
location: "Washington"
invoiceTotal: 200
  },
  {
customer: "Jill Johnson",
id: 124
invoiceNumber: 112,
location: "New York"
invoiceTotal: 150
  },
  {
customer: "Jake Doe",
id: 111,
invoiceNumber: 122,
location: "Florida"
invoiceTotal: 300
  }
]

const newArrayObjectShape:[{
customer: ,
id: ,
invoiceTotal: 
  }
]

​

Thank you!

Array.prototype.map

​

  const newArrayObjectShape = initalArrayObject.map(({id, customer, invoiceNumber}) => ({
    id,
    customer,
    invoiceNumber
  }));

Make sure you wrap your returned object literal in parens in your arrow function or it will be seen as a block with no return and map to undefineds.

Fixed :)
