JavaScript this Keyword Explained Simply

The “this” keyword allows you to decide which object should be focal when invoking a function or a method; effectively allowing you to reuse functions with different contexts.

const user = {
  name: "Sam",
  getName() {
    return this.name;
  },
  makeReader() {
    return () => this.name;
  }
};
const reader = user.makeReader();
console.log(user.getName());
console.log(reader.call({ name: "Mira" }));
