/**
Conditional promise chains. It's just a passthrough if `condition` is `false` and `doElse` is not provided.

@param condition - Decides whether `doIf` or `doElse` is executed.
@param doIf - Executed if `condition` is `true`. Expected to return a `Promise` or value.
@param doElse - Executed if `condition` is `false`. Expected to return a `Promise` or value.
@returns A [thunk](https://en.wikipedia.org/wiki/Thunk) that returns a `Promise`.

@example
```
import pIf from 'p-if';

getData()
	.then(pIf(process.env.NODE_ENV !== 'production', addDebugInfo))
	.then(data => {
		console.log(data);
	});

// Can also be nested:

getList()
	.then(pIf(shouldSort, pIf(sortDirection === 'ascending', sort.asc, sort.desc)))
	.then(list => {
		console.log(list);
	});
```
