JavaScript objects from a Java developer’s perspective

One of the challenges for Java developers to learn and implement a very different interpretation of “object” in any language. I find it easy to switch between Java and the context of switching languages ​​between Java and JavaScript such as Groovy, Ruby, Python, C #, and C ++. The other language for object-based approaches to orientation classes is that their main syntax and context switch is relatively similar to the very idea to learn. In many ways, the object-oriented prototype-based approach is very different, such as Java in JavaScript syntax is higher than some of these languages. In this post, I bridge Java developers can see a better perspective JavaScript uses “objects” and I provide some tips and tricks I object-oriented Java developer JavaScript and object-oriented concepts Java.

Java and javascript

Whereas Java and various and rich Data types primitive arrays including only a small amount of JavaScript (Boolean, number, string, null and undefined), data structures), and JavaScript support (a collection of data types and types of collections in many other programming languages) thing. It is easy to learn these basic range Data types collections, but this does not mean that additional tasks (or frameworks) are required to carry out some of the functions that other types and collections of languages ​​can provide.

JavaScript object constructor function for instant approach

There are several approaches to JavaScript direct objects. As a Java designer, I like the “constructor work” approach. The most bit of leeway is that the key used to go with this methodology of utilizing products can be utilized by the name for their utilization and the same number of parts of the code as accessible. In any case, as a Java engineer, this methodology doesn’t engage me, as it used to be, for example, Java (and different dialects dependent on object-situated classes).


Include a toString () JavaScript object

In the past depiction of the screen, both the names that show up in the support are appeared as “[object Object]”. Like Java, basic object augmentations are called item questions in JavaScript. Specifically, all JavaScript items get the Object. model object property. For this situation, Object.prototype.toString () gives the default portrayal to an item from a string in JavaScript. As a preview of the screen show, this is just a base worth (eg acquired from Java as stuff got in Java).
