So I have two types B and A, and an array a, which I should transform into type B.
type A = Array<[string, number, string]>;
type B = {
[name: string]:
{
name: string,
age: number,
city: string
}
}
const a: A = [
['name1', 10, 'city1'],
['name2', 33, 'city2'],
['name3', 61, 'city3'],
['name4', 60, 'city4']
];
export const b: B = ???
I have no understanding how can I transform an array because of index signature [name: string] in type B. Usually I transform through array.map(value => {}), but here I can't find a way to include index signature in map method.
B describes an object of the shape:
export const b: B = {
name1: {
name: 'name1',
age: 10,
city: 'city1'
}
};
but if you want an array of Bs you can
export const b: B[] = a.map(([name, age, city]) => ({ [name]: { name, age, city } }));
