Angular 21 Tutorial in Hindi #25 | Computed Signals - Full Name & Cart Total Examples

In this video, we explore Computed Signals — one of the most powerful features in Angular’s new reactivity model. Computed signals automatically update when their dependent signals change. We cover how computed works, basic examples, full-name example, cart total calculation, and real-world use cases. A must-know feature for building clean, reactive, maintainable Angular applications. 📘 What You’ll Learn in This Video -- What are Computed Signals? -- How computed works internally -- Basic computed example -- Full name example: firstName + lastName -- Cart total example using array signals -- Why computed is important for reactivity -- Best practices for computed signals -- Beginner-friendly interview questions ⚙️ Tech Used Angular 21, Angular CLI, Node.js, VS Code, Terminal 📢 *Resources:* 👉 *Angular Documentation* - https://angular.dev/overview 👉 *GitHub Code Link* - https://github.com/mohitdjcet/angular21-tutorial 📂 *Playlist Links:* - Angular 21 Full Course Video (Hindi): https://www.youtube.com/playlist?list=PLsjpRo2EZP1LTrYY6_FMpx6cqmjuPdoo2 - JavaScript Full Course Video (Hindi): https://youtu.be/moRFcW7xayc - Python Full Course Video (Hindi): https://www.youtube.com/playlist?list=PLsjpRo2EZP1Ja-GuGvkiPqmE3RGYP4lnI - Django Full Course Video (Hindi): https://www.youtube.com/playlist?list=PLsjpRo2EZP1K_glKX0lG6BkviJFxjuGls - NodeJS Full Course Video (Hindi): https://www.youtube.com/playlist?list=PLsjpRo2EZP1Lv7wu42U1Z-_Omh-pcjsUv - Git and GitHib Copilot Full Course Video (Hindi): https://youtu.be/hebwERejgI4 🔗 *Follow Me for Updates:* - TopMate:[Connect with Me](https://topmate.io/mohitdecodes) - WhatsApp:[Connect with Me](https://whatsapp.com/channel/0029Vb6CABUIHphQqGRYP71u) - Instagram: [Connect with Me](https://www.instagram.com/mohit_decodes/) - Facebook: [Connect with Me](https://www.facebook.com/mohitdecode/) - LinkedIn: [Connect with Me](https://www.linkedin.com/in/mohitdecodes/) - GitHub: [Explore My Projects](https://github.com/mohitdjcet/) angular computed signals, computed signal example, angular signals tutorial, angular 21 reactivity model, computed full name example, cart total computed angular, angular computed vs signal, typescript computed signals angular, angular 21 full course hindi, mohit decodes angular #mohitdecodes #angular21 #angular #computedsignals #signals #reactivity #frontend #javascript #typescript #webdevelopment #hinditech --- Copyright Notice: © Mohit Decodes.
