Mastering the Arcane Art of JavaScript-Mancy for C# Developers - Chapter 7: Using LINQ in JavaScript

What if I told you that JavaScript has LINQ? In the past few articles we’ve looked into functions in JavaScript, we’ve seen how to work with functions and used different patterns and practices. Today we are going to take that knowledge and apply it into the realm of functional programming. We’ll start dipping our toes into functional programming by taking a look at how we can use LINQ in JavaScript. LINQ (Language-Integrated Query) is a .NET query language that lets you work seamlessly with collections of objects (and other data sources). It revolutioned .NET by bringing functional programming concepts to the masses and providing an alternative to the prevalent imperative style programming in C#. JavaScript offers different ways in which we can achieve that same LINQ-style queries: array prototype functions, ES2015 generators, third-party libraries and ES2016 comprehensions. Let’s take a look at them!
