New JavaScript Features improving the Web Design World 
Published: 2021-08-11 17:10:07

The new decade has been a year of discovery and introduction of novice features for web developers and programmers. JavaScript has been on the forefront of these innovations and system developments. In the current world, JavaScript has been defined as a well-thought-out programming language based on its user-friendly code and versatility. JavaScript platforms and tools are well recognized and globally appreciated for creating top-notch and cutting edge online casino games available in sites such as [onlinecasinosincanada.ca](http://onlinecasinosincanada.ca/). 

Programmers and online casino games developers agree that JavaScript platforms creates fully-fledged games that offer the most fascinating user experience and the start of the art of security. The best part of JavaScript is the capacity to develop new features in constant frequentness with the aim of aiding their clients have the best experience and create more powerful, reliable, and efficient sites and applications. Let’s take you through some of the new JavaScript features that will enable the development of super cool online casino games. 
 
###Dynamic import

This new JS feature saves us the challenge of importing files as modules. The most intriguing factor about this feature is how it enables the use to ship-on-demand request codes or conduct a code splitting function without the unnecessary module bundlers or even the overhead of web pack. It helps in making an import without adulterating the global namespace. 

Dynamic import is a syntax that has solved the ever-evolving problems of failing to dynamically produce the parameters of import. Users have widely expressed their contention in regards to the dynamic import capacities that include the factor that it can be called from any place in the code and that it returns a promise that resolves into a module object. The previous features that are made in static means that developers will use more compile-time checking while the dynamism aspect provides for analyzable information at a lesser build time. Dynamic import enhances the use of one bundle for a single app and this enables sites built through JavaScript to be faster and efficient for demanding tasks such as the online casino games. 

###BigInt

BigInt value or popularly known as BigInt is a new addition to the JavaScript programming that adds integer value or string value to the integers. It simply means that the feature gives developers the power to have greater integer representation as they code with JavaScript for improved data processing during data handling procedure. 

The feature operates by adding an appended n at the end of the numeral to give the JavaScript engine the notion of treating it differently allowing the engine to support numbers of larger sizes. Strong sites such as online casino websites require a code that allows larger and more integers to reduce downtime and create more value for the user. 

###Nullish coalescing 

For a longer period developers have had the challenge of assigning values to be either false or null due to predictability hardships. But not anymore, the nullish coalescing feature provides through and efficient specification of assigning values. The feature handles default values through short-circuiting operators by assigning them as “truthy” or “falsy”. For instance, if a code is assigned to the left-hand side, it is considered as false while in the right-hand side it is considered as truth without leading to bugs. 

Developers enjoy an added advantage of in that nullish coalescing evaluates its operands at most once which means it reduces the time used for evaluation increasing the value and reducing time used. For online casino web developers, this is a simple and invaluable addition to their repositories that will enable efficiency, predictability, and clean coding.
 
###Prototype based programming 

Prototype-based programming refers to the object-oriented programming design where the behavior re-use involves cloning and extending objects and re-using them to serve as prototypes. This distinctive procedure gives objects the capacity to just inherit from other objects directly as opposed to creating something from nothing. 

This feature gives [programmers using JavaScript language](http://www.forbes.com/sites/forbestechcouncil/2017/03/14/what-language-should-budding-programmers-learn-first/) the opportunity to create more objects by just cloning the initial ones. Cloning for this case is viewed as a style of developing new objects by simply copying the behaviors of an existing object where the clone or the prototype carries the qualities of the original object. This is a simpler, faster, and more efficient process that gives developers an upper hand in their activities. 

###Import.meta

Import.meta is a uniquely designed feature that allows the object to provide precise metadata elements to the defined JavaScript module. This feature is known for bringing out or exposing the information about the module and in this case the information may include the module’s URL and resolve. For the URL obtained can be from the script; that is for external scripts, or it can be document base URL for the inline scripts. 

An important thing to note is that the obtained URL will provide other details such as the query parameters or hash. [Programmers also need to understand](https://dev.to/hrishikesh1990/using-python-to-print-variable-in-strings-1d11) that the import meta object was created using the ECMAScript implementation. 

###Optional chaining

This remains among the most fascinating features that have been recently introduced into the JS programming language. Previously, identification of a deep-rooted value has been a humongous challenge since you have to check if the intermediate node exist. Another challenge has been that the object maybe assigned as undefined or null but you want to get the result when the object is defined. 

As a result, the optional chaining feature gives the user the ability to read the value of a property that is deeply located in a cycle of inter-joined objects without necessary having to [check](https://www.deviantart.com/us-news/posts) the validity of each reference within the chain. Developers note that optional chaining is a syntax with the capacity to access deeply nested object properties without being concerned of their existence. 

Basically, it provides shorter expressions due to its short-circuiting capacities which eliminates the error reference. The other advantage of this feature is that it aids in the exploration of object context in cases when there is no guarantee of the properties.
