Sort an array of objects in typescript?

Question

Simplest way for me is this:

Ascending:

arrayOfObjects.sort((a, b) => (a.propertyToSortBy < b.propertyToSortBy ? -1 : 1));

Descending:

arrayOfObjects.sort((a, b) => (a.propertyToSortBy > b.propertyToSortBy ? -1 : 1));

In your case,
Ascending:

testsSortedByNome = tests.sort((a, b) => (a.nome < b.nome ? -1 : 1));
testsSortedByCognome = tests.sort((a, b) => (a.cognome < b.cognome ? -1 : 1));

Descending:

testsSortedByNome = tests.sort((a, b) => (a.nome > b.nome ? -1 : 1));
testsSortedByCognome = tests.sort((a, b) => (a.cognome > b.cognome ? -1 : 1));
