const array: any = [{ test: 10 }, { test: 'test' }, {test: true}];
console.log(array.map(({ test }: {test: any}) => test));

output : [10, "test", true]

What you do is destructing argument and assign property to new value, instead you should do this:

.map(({ key }: { key: any }) => key);

I would suggest to read more about TS in handbook
