React Native - 如何合並用戶項目並顯示在他的個人資料上？

Question

我有的：

{"name": "author-1", "slug": {"_type": "slug", "current": "author-1-slug"}}
{"name": "author-2", "slug": {"_type": "slug", "current": "author-2-slug"}}
{"name": "author-1", "slug": {"_type": "slug", "current": "author-1-slug"}}
{"name": "author-3", "slug": {"_type": "slug", "current": "author-3-slug"}}

我想要的是：

{"name": "author-2", "slug": {"_type": "slug", "current": "author-2-slug"}}
{"name": "author-1", "slug": {"_type": "slug", "current": "author-1-slug"}}
{"name": "author-3", "slug": {"_type": "slug", "current": "author-3-slug"}}

我嘗試了什么：

const filtered = _.uniqBy(authors, 'slug')

//result [], [], [], []

有什么解決辦法嗎？

Answer 1

如果這是 lodash function，如果你不想有 2 個相同的作者，你應該這樣嘗試：

const filtered = _.uniqBy(authors, 'name')

Answer 2

const uniqueTags = []; authors.map((item) => { var findItem = uniqueTags.find((x) => x.name === item.name); if (!findItem) uniqueTags.push(item); });
