Typescript allows for the creation of arrays with transformed objects

I'm struggling with what seems like a simple question, but I can't seem to find an easy solution.

When working in Typescript, I need to manipulate each object within an array and return the modified array.

Here's an example:

foo = [{code: 1, desc:"a"},
       {code: 2, desc:"b"},
       {code: 3, desc:"c"}];

get Foo() {
   return this.foo.forEach((item) => {
       return {code:item.code + 1, desc: item.desc};
   });
}

However, this getter is returning undefined.

Can someone guide me on the correct approach to achieving my desired outcome?

Answer №1

When using the `forEach` method, it won't return any value, just like `undefined`.

To achieve a return value, consider using the `map` method instead.
