// immutability array
const newArray = numbers.filter(n => n != 2); // for removing element
const newArray = numbers.slice(0, index);
const newArray = [... numbers]; // for creating new array
const newArray = numbers.map(n => n === 2 ? 20 : n); // for updating array
// immutability objects const newObj = { ... oldObj }; const newObj = { ... oldObj, prop1: "test" }; const newObj = { ... oldObj, prop2: { ... oldObj.prop3 } }; // when you need deep cloning
// immer library is better than immutable (for immutability libraries)
// added proxy property to package.json in order for api calls to work
