### Invoke In Sequence Only The First And Last

This high-order function wraps an asynchronous function to

ensure controlled execution. When the wrapped function

is invoked, it starts executing immediately if it's the 

first call. However, if the function is called multiple

times before the first execution completes, only the last

call will be executed once the first execution finishes.

This mechanism ensures that no parallel executions occur,

and redundant calls are ignored until the initial

execution is complete.

```typescript

async function base(params): Promise {

    ...

}

const wrapped = invokeInSequenceOnlyTheFirstAndLast(base)

```
