What is Span in C# and why you should be using it

Hello everybody I'm Nick and in this video I am going to talk about Span of T in C#. Span was introduced in C# and .NET alongside a series of optimisations all the way back in .NET 2.1 and it has come to my attention that it is really confusing to understand if you just read the documentation for it. In this video I will break it down for you and help you understand exactly what it is, how it works and how you can use it in your applications today!

Hello everybody. As some people have already pointed out, after 13:50, when I'm returning a ReadOnlySpan, the ToString() on line 21 should be removed. I didn't notice because of the implicit operator. If you leave the ToString() in then you still allocate the string you return.

If int.Parse did not need to input string but span why Console.WriteLine need it?

Great video as always. Is this only ever useful for strings? Thanks

shouldn't you remove the tostring() from the yearastext? now it make's no sense.
