Quick Start

using DotNetExtensionKit;

// Strings
"Hello, World!".Truncate(5);           // "Hello"
"HelloWorld".ToSnakeCase();            // "hello_world"
"1234567890".Mask();                   // "12******90"
"Hello World!".ToSlug();               // "hello-world"

// Collections
var batches = new[] { 1, 2, 3, 4, 5 }.Batch(2);  // { {1,2}, {3,4}, {5} }
List<int>? items = null;
items.IsNullOrEmpty();                 // true
items.OrEmpty();                       // safe empty enumerable

// DateTime
var now = DateTime.Now;
now.StartOfDay();                      // today at 00:00:00
now.StartOfWeek();                     // most recent Monday
new DateTime(1990, 3, 25).Age();       // age in years

// General
"hello".Transform(s => s.Length);      // 5
5.IsBetween(1, 10);                    // true
"b".IsIn("a", "b", "c");              // true
