$linq is a Javascript version of .NET's Linq to Objects, with some query operations inspired by MoreLinq

Some of the Linq to Objects methods implemented

  • select
  • selectMany
  • where
  • orderBy
  • thenBy
  • distinct
  • groupBy
  • groupJoin
  • join
  • except
  • union
  • intersect
  • take/takeWhile/takeUntil
  • skip/skipWhile/skipUntil
    Examples
A simple example of breaking up a sequence of numbers into even and odd arrays:

var list = $linq([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);

var evens = list.where(function (x) { return x % 2 == 0; }).toArray();
var odds = list.where("x => x % 2 == 1").toArray();

PostgreSQL 17 منتشر شد
PostgreSQL 17 Released — The big one is here. It's the newest major version of Postgres, and it takes a bigger step forward than even v16. Some of what’s new:
  • Overhauled memory management for vacuuming, resulting in significantly lower memory usage and running time. More on this here.
  • Incremental backup support.
  • Faster B-tree index scans.
  • MERGE enhancements, including view support.
  • New functions to extract elements from UUIDs.
  • WAL improvements – up to 2x write throughput on some workloads.
  • Improvements to SQL/JSON support, including JSON_TABLE.
  • Bulk loading improvements and perf improvements for COPY which gains the ON_ERROR ignore option to ignore errors.
  • Identity columns on partitioned tables.

دوره پیاده سازی minimal API با دات نت 7

.NET 7 minimal API from scratch | FULL COURSE | clean architecture, repository pattern, CQRS MediatR

In this course I want to provide you a project structure and code organization to get you started with real .NET 7 minimal API projects. It's a full course on this topic where I start from creating and explaining the project structure, setting up different layers using EF Core, repository pattern, CQRS and MediatR. The biggest part of the video is however around the .NET 7 minimal API, taking you from the initial setup, explaining route handlers, implementing all CRUD operations and so on. Last but not least, this course walks you through the process of refactoring the .NET 7 minimal API so that it becomes readable, maintainable and scalable. At the end, you'll have a full project structure organized according to modern architectural patterns that you can take as a template for your own projects.
