Closures Development Tutorials, Guides & Insights

• Constructor Function Call: When using the new keyword to create an object, this refers to the newly created object.

  function Person(name) {
      this.name = name;
  }

  const person = new Person('John');
  console.log(person.name); // Output: John

Closures are essential because they enable powerful and flexible programming techniques. They allow you to:

• Encapsulate private data: Closures can help you create data that cannot be accessed directly from outside the function.
• Create factory functions: Closures can generate functions with specific behaviors or data preloaded.
• Maintain state across function calls: Closures allow you to maintain and manipulate the state of variables across multiple function calls.
