TypeScript Recipes vs Learn NestJS

• Learn programming with the best code recipes. • TypeScript: - How to get a substring? - How to declare a generalized method? - How to perform a database query? • SQL: - How to combine multiple tables in a single query? - How to sort the result of grouping data? - What types of data are available in SQL Server? • The best examples of code from books and specific Internet resources are selected in the app. Finding a good solution on the Internet can take hours of work. Ready-to-use and tested “recipes” for code are included in the application. • The app is an excellent tool for preparing for exams or interviews. It helps you understand the typical tasks you might encounter. • One app for iOS and macOS. Buy it once and use it on your phone, tablet, or computer. • Quick search for the correct example by code or topic name. • All the examples in the app are available offline. You can use the app even if there's no internet connection. If you can help translate the app into your language, please let me know by email.

Master NestJS, the progressive Node.js framework. Built with TypeScript and inspired by Angular, NestJS provides an out-of-the-box architecture for creating highly testable, scalable, and maintainable server-side applications. Whether you're new to backend development or leveling up from Express, this is your complete path to becoming a professional NestJS Developer.
