Is there a way to create a new object using the map function on employees in TypeScript without declaring a variable?
employees.map(x=> ({name: x.firstName}));
This way, I can have VSCode intellisense while making my new object. However, if I try
employees.map(x=> {name: x.FirstName});
I lose the ability to see available properties while typing. Apologies if my question is unclear.
A map function allows you to define the return type:
employees.map<Person>(x=> ({name: x.firstName}));
To handle type assertions in TypeScript, you can use the following approach:
employees.map(employee => ({ name: employee.FirstName } as Person));
Understanding the category of workers, enables you to perform the task easily by following this straightforward approach:
employees.map((x: Employee)=> {name: x.FirstName});
It seems like you are storing the result of map in a variable. If you specify the type for that variable, Intellisense should recognize it. Here's an example:
interface Person {
name: string;
}
const users = [{ first: "Alice" }, { first: "Bob" }, { first: "Charlie" }];
const people: Person[] = users.map(u => ({ name: u.first }));
