A Small Example with the Axios.get() Method

export default {
data(){
    return{
        users:null, // I created an empty variable named users
    }},
  methods:{
    function (){
    axios.get('https://jsonplaceholder.typicode.com/users').then((response) => { 
    // we fetch the api and use the then() method for further operations
     this.users = response.data; // we accessed the data object within the returned response and assigned it to the variable named users
     console.log(this.users); // now we logged the returned results to the console
     })
