Conditional application of chained LINQ queries

stp2y0 CommentsNewscoding, community, csharp, development, dotnet, engineering, inclusive, programming, software

I write C# and I'm a big fan of using LINQ to create nice, readable chains of operations to filter and transform data in a functional style. int HighestEvenNumber(IEnumerable<int> numbers) => numbers .Where(x => x % 2 == 0) .OrderByDescending(x => x) .FirstOrDefault(); Enter fullscreen mode Exit fullscreen mode Sometimes though, there are conditions where parts of the chain should be included or omitted, but breaking the chain to add an if-statement feels wrong and disruptive. Let's say our previous example should throw an exception if there are no even numbers in the sequence instead of returning the default int…

I was wrong about keys and collections

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, react, software

Almost every React developer has gone through the Main Concepts documentation from React website. If you have done that, you must have read chapter 8, which is about Lists and Keys (https://reactjs.org/docs/lists-and-keys.html). You end up understanding that, to use lists in React properly, you need to make use of a key on your components. But why? Well, there’s a brief explanation in there: Keys help React identify which items have changed, are added, or are removed. Keys should be given to the elements inside the array to give the elements a stable identity. Isn’t that easy? At that moment, if…
