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 anonymous function
let show = function () {
console.log('Anonymous function');
};
//… can be shortened using the following arrow function:
let show = () => console.log('Anonymous function');
//Similarly, the following anonymous function:
let add = function (a, b) {
return a + b;
};
//is equivalent to the following arrow function:
let add = (a, b) => a + b;Copyright © 2021 Codeinu
