Imperative vs Declarative (How vs What)

imperative (how)

const h1 = document.createElement("h1")
h1.textContent = "Hello world"
h1.className = "header"
console.log(h1)

declarative (what)

// JSX
ReactDOM.render(<h1>This is JSX</h1>, document.getElementById("root"))

Generally, “declarative” programming is preferred, and they cause fewer bugs.

Book: Big Data: Principles and best practices of scalable realtime data systems

The main idea of the Lambda Architecture is to build Big Data systems as a series of layers. Each layer satisfies a subset of the properties and builds upon the functionality provided by the layers beneath it. The high-level ideas of how the whole system fits together are fairly easy to understand.

Google Tag Manager: https://tagmanager.google.com

Tag Assistant: https://tagassistant.google.com/

Google Analytics: https://analytics.google.com

Google Tag Manager is a tag management system (TMS) that allows you to quickly and easily update measurement codes and related code fragments collectively known as tags on your website or mobile app. Once the small segment of Tag Manager code has been added to your project, you can safely and easily deploy analytics and measurement tag configurations from a web-based user interface.

Tag Manager container

A collection of tags, triggers, variables, and related configurations installed on a given website or mobile app is called a container. A Tag Manager container can replace all other manually-coded tags on a site or app, including tags from Google Ads, Google Analytics, Floodlight, and 3rd party tags.

Each Google Analytics 4 property can have up to 50 data streams (any combination of app and web data streams, including a limit of 30 app data streams).

A data stream is a flow of data from a customer touchpoint (e.g., app, website) to Analytics.
