Report: "Dawlat al-Islam Qamat" (The Islamic State Has Risen)

Subject: Anasheed (Vocal Hymn) associated with the Islamic State (IS) Status: Prominent jihadist propaganda material Language: Arabic

The message of "Qamat" is particularly relevant in today's world, where many Muslims face persecution, marginalization, and oppression. The nasheed serves as a beacon of hope, reminding listeners that they have the power to create positive change in their communities. By calling for the establishment of an Islamic state, Dawlat Al Islam is not advocating for a rigid or oppressive system but rather a society that upholds the principles of justice, equality, and compassion.

For groups such as the Islamic State (IS), propaganda is not merely a supplementary tool but a central pillar of their existence. Among the various forms of media employed—ranging from high-gloss videos to online magazines—the nasheed stands out as a uniquely effective cultural vector.

Descriptive content, continous updates, and soundbites from industry professionals.

Descriptive, not prescriptive

When explaining content, we follow a descriptive approach, not prescriptive. In other words, we don’t tell you what specific tools or libraries you have to use to be successful. Rather, we focus on explaining a concept and employ certain libraries or tools to illustrate that concept.

React-focused with universal concepts

While the book is React-focused, it teaches universal concepts that transcend all web development frameworks. It's designed to enhance your understanding of building web applications that are scalable, maintainable, and adaptable, regardless of the specific technology stack.

Continous, frequent updates

Purchasing the e-book gives you access to all new content, edits, and improvements forever. In fact, we're currently working on adding three new chapters soon — Routing, User-centric API design, and React in 2024. Check out the Changelog to follow along on all the updates we'll make.

Soundbites from industry professionals

In the book, we share soundbites and thoughts from industry professionals. These soundbites are shared from start-up owners and software engineers who work at Doordash, Netflix, Spotify, and more.
