What is a “container snippet” in Tag Manager?

The container snippet is the JavaScript code you place on every page of your website. This snippet asynchronously loads the Google Tag Manager container, enabling it to fire tags and collect data. Without this snippet, Tag Manager cannot function on your site. A JavaScript object that holds data passed from your website describes the data layer, not the snippet itself. A collection of website tags and triggers describes the container, which the snippet loads. Analytics tracking code is a specific type of tag that can be deployed via Tag Manager, but it's not what the container snippet is.
