数组拆分

• 将一个数组按一定规则拆分成两个数组

//第一个数组前五条，剩下的分在第二个数组里
baseArray:[
                {
                    name: '10'
                },
                {
                    name: '20'
                },
                {
                    name: '30'
                },
                {
                    name: '40'
                },
                {
                    name: '50'
                },
                {
                    name: '60'
                },
                {
                    name: '70'
                },
                {
                    name: '80'
                },
                {
                    name: '90'
                },
                {
                    name: '100'
                }
            ],
            oddArr: [],
            eventArr: []


       getArr(){
            this.oddArr = this.baseArray.slice(0,5)
            this.eventArr = this.baseArray.slice(5)
        },

• 奇数偶数拆分

baseArray:[1,2,3,4,5,6]
getArr(){
        this.oddArr = this.baseArray.filter((item)=> item % 2 === 1)
        this.eventArr = this.baseArray.filter((item)=> item % 2 === 0)
        },
