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

} else {
return None;
}
})
.getOrElse(() => accumulator.push([ currentCommit.authorName, List([ currentCommit ]) ]))
}, List<[string, List<GitHubCommit>]>())示例2: headOption

.map(commit => (
h('li', [
h('a', { href: commit.url }, headOption(commit.message.split('\n')).getOrElse(() => '')),
