why can't you use arrow function with this in javascript for declaring methods
'use strict';
var obj = { // does not create a new scope
i: 10,
b: () => console.log(this.i, this),
c: function() {
console.log(this.i, this);
}
}
obj.b(); // prints undefined, Window {...} (or the global object)
obj.c()js arrow function vs function
// currently common pattern
var that = this;
getData(function(data) {
that.data = data;
});
// better alternative with arrow functions
getData(data => {
this.data = data;
