It's two parts as I understand it -- a common standard for writing code that works through collections in a functional/chaining way (the code you posted), and a syntax in C# that lets you write linq queries in a syntax that is reminiscent of SQL.

The first part is just easier to read and write for the most part. The second part I guess is nicer too? I'm not a C# dev.

nah, linq lets you use functional programming idioms in .net

some of them happen to be named similarly to similar concepts in sql

nah, you gotta look past the sql-like syntax poo poo. The power is when you have a collection of Turd (like List<Turd>) and you do stuff like:

TurdList.Select(turd => turd.ID.ToString()).Where(turd => turd.Color == Color.Green).ToList().

Normally, if you wanted to extract all the ID's as strings from green Turds, you'd have a foreach loop with if-logic that checks the Color and a ToString() and don't forget your placeholder variables etc.etc.etc.

Or, if you just want to know RIGHT NOW if there are any brown turds:

TurdList.Any(turd => turd.Color == Color.Brown)

And that's just the basic stuff. When you start doing .Join(), .Union(), .Intersect(), and poo poo like that stuff can get weird, man. But it's a good weird, ya know?

JawnV6: Jul 4, 2004; So hot ...

a for loop is like hiring a fancy architect to build your house, then pedantically explaining where you want every individual stud to be placed

linq is saying "i want a kitchen, living room, and master bath" and letting the architect figure out the implementation details

you're specifying "what" you want, not "how" to do it

linq is the best thing about c#

# ? Mar 22, 2016 23:17

brap: Aug 23, 2004; Grimey Drawer

the other neat thing about lambdas/linq is that c# has expression trees so you can basically write "functions" in c# that are really expression trees that get compiled to sql at runtime and... well, it's a mixed bag, actually.

linq and async/await...and ASP.NET...are the reasons for using C#.
you just have to live with windows or a windows VM to use it.

I'm real bad at creating long linq chains so I got into the habit of trying to format/comment complicated ones for maintenance sake. But man it's soooo good when you take a bunch of function calls and logic and turn it into a single linq statement and almost never have to touch it again because the work is in separately defined predicate/map methods :hellyeah:

in the vein of npm having retarded packages, look at this other vital package for nodejs:
https://github.com/tjmehta/is-positive-integer

JavaScript code:

Usage

var isPositiveInteger = require('is-positive-integer')

isPositiveInteger(1) // true
isPositiveInteger(10) // true
isPositiveInteger(100) // true
isPositiveInteger(1000) // true
isPositiveInteger(0) // false
isPositiveInteger(-1) // false
isPositiveInteger(-10) // false
isPositiveInteger(-100) // false
isPositiveInteger(-1000) // false
isPositiveInteger(1.1) // false
isPositiveInteger(10.1) // false
isPositiveInteger(100.1) // false
isPositiveInteger(1000.1) // false
isPositiveInteger(-1.1) // false
isPositiveInteger(-10.1) // false
isPositiveInteger(-100.1) // false
isPositiveInteger(-1000.1) // false
isPositiveInteger(Infinity) // false
isPositiveInteger({}) // false
isPositiveInteger([]) // false
isPositiveInteger('10') // false
isPositiveInteger('what') // false
isPositiveInteger(/what/) // false

the source code for this incredible module is:

JavaScript code:

var passAll = require('101/pass-all')
var isPositive = require('is-positive')
var isInteger = require('is-integer')

module.exports = passAll(isPositive, isInteger)

So how many things depend on it and is there anything important going up?
