I will cover LINQ methods for initializing a sequence.

Here are the methods covered so far.

1. Part 1 〰️ Select, Aggregate, Where, OrderBy (Ascending, Descending)
2. Part 2 〰️ Any, Distinct, Concat, SelectMany
3. Part 3 〰️ Reverse, Zip, Min/Max
4. Part 4 〰️ Union, Intersect, Except
5. Part 5 〰️ Sum, Average, Count
6. Part 6 〰️ First, Last, DefaultIfEmpty, Skip, Take
7. Part 7 〰️ Empty, Repeat, Range
8. Part 8 〰️ All, Contains, SequenceEqual

I’ve covered “min” and “max” in part 3 so I won’t cover them again here.

LINQ has been around since 2007. It made the code more readable as you specify what you do with a collection not how to process it.JavaScript is the de facto standard so you should be working with it often if you are doing web development.

I will share some “approximate” JavaScript equivalents below for those working primarily with .NET but want to use the existing skill in JavaScript.

Since each method do not match exactly one to one functionality wise, I will drop “approximate” hereafter.

Here are the methods covered so far.
