export default {
    name: "Computed",
    data() {
        return {
            firstName: "pan",
            secondName: "rui",
            threeName: "hello",
        }
    },
    computed: {
        fullName: function () {
            console.log("是否重新计算")
            let string = this.threeName + "love"
            return this.firstName + " " + this.secondName
        }
    },
    methods: {
        changeFirstName: function () {
            this.threeName = "zhu"
        }
    },
}
