linqjs的常用方法

var myList = [
{ Name: "Jim", Age: 20,type:1 },
{ Name: "Kate", Age: 20 ,type:2},
{ Name: "Lilei", Age: 18,type:1 },
{ Name: "John", Age: 14,type:2 },
{ Name: "LinTao", Age: 25,type:1 }
];
//var arrRes = linq.from(myList).where("x=>x.Name=='John'").toArray();//条件查询
//var arrRes = linq.from(myList).select("x=>x.Age*10").toArray();//条件选择
//var arrRes = linq.from(myList).orderBy("x=>x.Age").toArray();//排序
var arrRes = linq.from(myList).distinct("x=>x.Age").where("y=>y.type=='2'").toArray();//去重
//var arrRes = linq.from(myList).forEach(function (value, index) {//循环
//    console.log('value:'+value.Name+' =======index : '+index)
//});
//var arrRes = linq.from(myList).firstOrDefault('x=>x.Age>18');//取唯一对象：First、FirstOrDefault、Last、LastOrDefault、Single、SingleOrDefault
//var arrRes=linq.range(1,10).skip(5).toArray();//结果[6,7,8,9,10]
//var arrRes=linq.range(1,10).take(5).toArray();//结果[1,2,3,4,5]

var array1 = [1,412,5,3,5,412,7];
var array2 = [20,12,5,5,7,310];
//var arrRes=linq.from(array1).except(array2).toArray();//结果3,412,1 差集
//var arrRes=linq.from(array1).intersect(array2).toArray();//结果5,7  交集
//var arrRes=linq.from(array1).union(array2).toArray();//结果是两个结果集里面所有值，并自动去重

//var arrRes=linq.range(1,10).where('x=>x%2==0').toArray();
