filter（）数组过滤

filter（）方法对数组进行过滤，不会改变原数组的

js数组过滤

let nums = [1,2,3,4,5,6,7,8,9,10];

let res = nums.filter((num)=>{

        return num>5 ;

})

console.log(res);

vue数组过滤

{{ n }}

data(){

        return {

                numbers: [ 1, 2, 3, 4, 5 ]

        }

},

computed:{

        evenNumbers: function () {

                return this.numbers.filter(function (number){

                        return number<4

                })

        }

}
