What is the output of the following? “`js const obj = { value: 42, getValue: function() { return this.value; }, getValueArrow: () => this.value }; console.log(obj.getValue()); console.log(obj.getValueArrow()); “`

Accepted Answer

The output of the code is 42, undefined because the `getValue` method uses the `this` keyword to access the object's property, while the `getValueArrow` method uses an arrow function, which does not have its own `this` context.
