- **added** — Add getInitialMicrosteps() and getMicrosteps() functions that return an array of [snapshot, actions] tuples for each microstep in a transition

###### Minor Changes

-   [#5457](https://github.com/statelyai/xstate/pull/5457) [`287b51e`](https://github.com/statelyai/xstate/commit/287b51eb80abc521f8c35fa73df177a0b9dfd3bc) Thanks [@davidkpiano](https://github.com/davidkpiano)! - Add `getInitialMicrosteps(…)` and `getMicrosteps(…)` functions that return an array of `[snapshot, actions]` tuples for each microstep in a transition.

    ```ts
    import { createMachine, getInitialMicrosteps, getMicrosteps } from 'xstate';

    const machine = createMachine({
      initial: 'a',
      states: {
        a: {
          entry: () => console.log('enter a'),
          on: {
            NEXT: 'b'
          }
        },
        b: {
          entry: () => console.log('enter b'),
          always: 'c'
        },
        c: {}
      }
    });

    // Get microsteps from initial transition
    const initialMicrosteps = getInitialMicrosteps(machine);
    // Returns: [
    //  [snapshotA, [entryActionA]]
    // ]

    // Get microsteps from a transition
    const microsteps = getMicrosteps(machine, initialMicrosteps[0][0], {
      type: 'NEXT'
    });
    // Returns: [
    //  [snapshotB, [entryActionB]],
    //  [snapshotC, []]
    // ]

    // Each microstep is a tuple of [snapshot, actions]
    for (const [snapshot, actions] of microsteps) {
      console.log('State:', snapshot.value);
      console.log('Actions:', actions.length);
    }
    ```
