MongoDB Tutorial

A MongoDB Document

Records in a MongoDB database are called documents, and the field values may include numbers, strings, booleans, arrays, or even nested documents.

Example Document

{
	title: "Post Title 1",
	body: "Body of post.",
	category: "News",
	likes: 1,
	tags: ["news", "events"],
	date: Date()
}
