JavaScript equivalents of some common C# LINQ methods. To help me remember!

JS-LINQ.js

var people = [ 
	{ name: "John", age: 20 }, 
	{ name: "Mary", age: 35 }, 
	{ name: "Arthur", age: 78 }, 
	{ name: "Mike", age: 27 }, 
	{ name: "Judy", age: 42 }, 
	{ name: "Tim", age: 8 } 
];

// Where
var youngsters = people.filter(function (item) {
	return item.age < 30;
});

// Select
var names = people.map(function (item) {
	return item.name;
});

// All
var allUnder40 = people.every(function (item) {
	return  item.age < 40;
});

// Any
var anyUnder30 = people.some(function (item) {
	return  item.age < 30;
});

// reduce is "kinda" equivalent to Aggregate (and also can be used to Sum)
var aggregate = people.reduce(function (item1, item2) {
	return  { name: '', age: item1.age + item2.age };
});
console.log(aggregate.age); // { age: 210 }

// sort is "kinda" like OrderBy (but it sorts the array in place - eek!)
var orderedByName = people.sort(function (a, b) {
	return  a.name > b.name ? 1 : 0;
})
