```typescript var a = { firstName: 'Bill', lastName: 'Ivanov', sayName: function() { console.log(this.firstName); }, sayLastName: () => { console.log(this.lastName); } }; a.sayName(); // var b = a.sayName; b(); // a.sayName.bind({ firstName: 'Boris' })(); // a.sayName(); // a.sayLastName(); // a.sayName.bind({ firstName: 'Boris' }).bind({ firstName: 'Tom' })(); // a.sayLastName.bind({ lastName: 'Petrov' })(); // ``` The containing arrow function captures the global value of 'this'.
