[Vuejs]-Calling "this" within Vue is returning Window

I think the problem is in the arrow function =>: it does not have its own bindings to this or super, and should not be used as methods (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions).

To bind this to a method use function long or short notation.

Long notation:

const app = new Vue({
    el: '#providers', 
    data: {
        providers: []
    },
    created: function () {
        console.log(this);
    },
})

Short notation:

const app = new Vue({
    el: '#providers', 
    data: {
        providers: []
    },
    created() {
        console.log(this);
    },
})
