Everything which I've searched is always without/ignoring order.
I want to pare 2 arrays with order.

expect([1, 2, 3].concat(4)).toEqualWithOrder([1, 2, 3, 4])

expect([{ value: 1}, { value: 2}, { value: 3 }].concat({ value: 4 })
.toEqualWithOrder([
  { value: 1 },
  { value: 2 },
  { value: 3 },
  { value: 4 },
])

How can I do that with Jest? Should we use JSON.stringify?

Just use the normal .toEqual method. It does require the items to appear in the same order.

Only to deviate from that you'd need a special method.
