# scheduleMicrotask method

void scheduleMicrotask (void callback())

Runs `callback` asynchronously in this zone.

The global `scheduleMicrotask` delegates to the current zone's scheduleMicrotask. The root zone's implementation interacts with the underlying system to schedule the given callback as a microtask.

Custom zones may intercept this operation (for example to wrap the given `callback`).

## Implementation

    void scheduleMicrotask(void callback());
