JS Constructor Method

Constructor functions in JavaScript are regular functions designed to create objects efficiently. They follow two conventions: starting with a capital letter and being executed using the new keyword. When invoked with new, the function creates and returns an object. This process replaces the need for repetitive object literals by allowing multiple objects to share the same structure, such as properties for name and age, which are defined using the this keyword.

The new keyword plays a vital role in defining how the function behaves, ensuring that it creates an object and binds this to that object rather than the global window. This makes constructor functions ideal for generating multiple objects with shared characteristics. By passing parameters to the constructor, unique objects can be instantiated efficiently, following conventions that enhance readability and consistency in JavaScript programming.
