JavaScript is one of the most powerful object-oriented programming languages used all over the world. This language uses the independent fragments of codes to build web applications. These fragments are known as objects that usually work as building blocks in any application. Using advanced objects in JavaScript is beneficial to model real-world elements that a programmer wants to represent in the program. From object-oriented to advanced expertise, JS is featured for its diverse capabilities and flexibility in the programming world.
Mentioned below are a few cutting-edge JavaScript objects:
· Namespaces
In most of the languages, we are well aware of the concept of namespaces, but JavaScript does not support this object. At some point, using namespace object is important for avoiding name conflicts. To overcome this limitation, one can add default global. The only need is to create a single global object for an application to hold all variables and functions as properties. With this, one can reduce the chances of name collision with any third-party library.
· Closures
Unluckily, JavaScript language does not support access modifiers which is the biggest issue for accessing the properties and methods. This means that all the objects are public and can be accessed from anywhere. By using closures, one can achieve the privacy to keep the “author” private without exposing them to the outer world. To do this, a function creates a local variable author which is accessible only within the function. The privileged method used for this is getAuthor().
· Constructors
As JavaScript does not support static and class variables to manage the private data of the object. This can be done by adding the shared members to the property of the constructor. In this approach, an instance is initialized by the constructor and environment holds the local variables and parameter. As a result, data in the instance can be accessible publically and the data available in an environment is only accessible by the constructor and functions which are created inside it.
· Modules
Modules in JS are used as small pieces of reusable code for building design patterns for any JavaScript-based language. Unfortunately, this programming language does not provide any kind of special keyword for packages to provide a way for classes. The solution for this complex issue is to use modules to organize the code in the better way. Another benefit of modules is that it modifies the internal functionality without affecting the rest of the code.
Advanced JavaScript objects have resolved all the implications that a programmer usually faces while implementing the apps. These objects are extremely useful to make the application run faster than ever.
