Update

Update

Update is a core part of MongoDB. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding update well means you can read other people's MongoDB code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What update means in the context of MongoDB
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with update

// MongoDB: Update
function demo() {
  console.log("Exploring Update in MongoDB");
}

demo();

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for update.
