Actually the object spread operator is part of ESNext, so no need to bring JSX up. And it's *so* much better than Object.assign to create immutable objects.
Basically,
const foo = { ...bar };
is equivalent to
const foo = Object.assign({}, bar);
but the former is more compact and readable than the latter.
