const isNotEmpty: boolean = ! accumulator.isEmpty();
const previousGroup = accumulator.last();

return maybePreviousAuthorName
.flatMap(previousAuthorName => {
if (previousAuthorName === currentCommit.authorName) {
const currentCommitsByAuthor = previousGroup[1];

return new Some(accumulator.set(index, [ previousAuthorName, currentCommitsByAuthor.push(currentCommit) ]))
} else {
return None;
}
})
.getOrElse(() => accumulator.push([ currentCommit.authorName, List([ currentCommit ]) ]))
}, List<[string, List<GitHubCommit>]>())示例2: headOption
.map(commits => headOption(commits.toArray()).map(commit => commit.authorName).getOrElse(() => ''))示例3: h
.map(commit => (
h('li', [
h('a', { href: commit.url }, headOption(commit.message.split('\n')).getOrElse(() => '')),
