Changing array in TypeScript/Angular

I'm attempting to transform an array of strings into an array of key-value pairs, like this:
["x", "y"] transforms into [{"Value":"x"}, {"Value":"y"}]

Any tips or guidance would be highly appreciated. Thank you!

Answer №1

One way to achieve this is by utilizing the map method:

const output = ['c', 'd'].map(element => ({ information: element });

Answer №2

Utilize Array#map:

const items = ["apple", "banana"];

const mappedItems: Array<{
    description: string
}> = items.map(item => {
    return {
        description: item
    };
})
