Code written by colleagues

function tableVue(tableData){
    var tableData = tableData;
    /* vue */
    var tableV = new Vue({  
        el: "-sharptable",
        data: {
            item:[]
        },
        mounted: function () {
            // 
            this.item = tableData;
        }
    });
}

then call this tableVue function when the page is initialized, and it works. But isn"t this tableV a local variable? Won"t virtual DOM nodes be destroyed with the destruction of this variable?
