Permanently assign `this` to a function

const obj = { name: "Codedrops" };

function greetings() {
  console.log(`Hi, ${this.name}`);
}

const bindGreetingToObj = greetings.bind(obj);
bindGreetingToObj(); // Hi, Codedrops

const obj2 = { name: "ABC" };
bindGreetingToObj.call(obj2); // Hi, Codedrops
