JavaScript

JavaScript Explained…

Sticky post

JavaScript is the programming language of choice of Generation X. It is lightweight , dynamic and gives independence of operating from either client or server side. It is an interpretive language that is object oriented. It is quite easy to program, at least on a beginner’s level. JavaScript is preferred by both professional and beginners. JavaScript Explained is the target of this brief analysis.

JavaScript History

JavaScript was originally developed by Netscape in order to add interactive dynamism to websites. JavaScript was released on December 4, 1995, as able to contribute to both server-side and client-side software. It was designed by Brendan Eich. It is event driven, functional, and imperative. There is a story behind its name. When JavaScript was created, it was called “LiveScript”, because it was meant to “liven” webpages. But in order to create a better positioning for this new product, and keeping in view the popularity of Java at that time, it was released as a kind of “younger brother” to Java, to cash in. But JavaScript soon became fully independent from Java, being structured around the specifications taken from ECMAScript. Today, JavaScript can execute in the Browser, the Server and on any device which is loaded with JavaScript Engine.

What is it, technically?

JavaScript has been defined variously as a dynamic computer language, a programming language used in web development. As a typical server-side scripting language, JavaScript can be inserted anywhere within the HTML of a webpage. . Thus it can update and change both HTML and CSS. JavaScript is a text-based programming language that can be used on both the client-side and the server-side. JavaScript converts a webpage to a dynamic and interactive experience for the User from the boringly static. JavaScript is an object-oriented programming language for ease of web development, enhancing the User experience to create responsive environments. Objects are variables which can be assigned many values. Arrays can be used to store multiple values in a single variable. JavaScript can calculate, manipulate and validate Data. It has only one type of Number. Numbers can be stored as with or without decimals. All numbers are stored as Double Precision Floating Point Numbers. Strings store text. Strings are written inside quotes (single or double quotes). The length of a string is found in the built-in property length.

JavaScript is close to Java, but the syntax is influenced by ECMAScript , which is similar to C and was developed by Sun Microsystems. Though usable on both ends, JavaScript is actually a client-side scripting language. Thus, it is the Client’s web browser that processes the Source Code. In other words, the JavaScript allows functions to run after a webpage has been loaded, without any communication from the server. Similar to ASP, PHP and other server side language for scripting, JavaScript codes can be used on a HTML webpage effortlessly. However, you need to remember that the Javascript codes are noticeable on the webpages and the server side codes are displayed as a result only.

Applications

JavaScript Engine can execute not only in the Browser, but also on the Server. In fact, it can execute on any device loaded with JavaScript Engine. The Browser often has an embedded engine, which may be called a “JS virtual machine”. The Engine reads or “parses” the script. Then it converts (or “compiles”) the script to machine language. Finally, the machine code runs, in very high speeds, optimizing as the program runs. Code names vary for separate engines, as follows:

  • As in Opera and Chrome: V8
  • As in Firefox: Spider Monkey
  • As in Microsoft Edge: ChakraCore
  • As in Safari: Nitro & SquirrelFish

Every type of software uses JavaScript, such as Productivity apps, Robotics, IoT (Internet of Things) devices, 3D Games etc. It can be used to build mobile applications and is commonly employed in everything from mobile games to free local sex apps. Dating apps specifically prefer JS due to its wide use, speed, and flexibility. Frameworks are available that can use JavaScript to build Android and iOS Apps. When compared to Python, JavaScript runs much faster. Python is better designed, but JavaScript runs on both browser and server, where Python is mostly used on server side programming.

There are over 1.6 Billion websites in the World, and JavaScript is used on 95% of them. In other words, 1.52 Billion websites run on JavaScript. And that is the Final Word on JavaScript explained.

Swift: A General Purpose Language Great For Mobile Development

Did you know that there are over 6500 languages in the world, yeah our world is gigantic, and you’ve probably only heard not even one third of all these languages, and that really says something. There are probably people that speak 5 the most, or even 10, 20, but there is no one that knows all of these languages, it is just not possible. Why? Because over 2000 of these languages are only spoken by 1000 people, so a very few amount as you can see.

However there are more languages than this. You may be wondering what? Well it’s not any language that we can speak, or write on a piece of paper so that people can understand it. These types of languages are the kinds you’ll find in programming, there are over 700 programming languages, and there is no way for you to know all of this. Learning one language is hard enough, but learning 700 is unthinkable. Some of the most common ones are C++, or Java Script, Python. These are the basic one that you will learn, but there is so much more than that. Like Swift, another programming language, you may not be familiar with the term, but it is used in some of the most obvious places.

Swift programming language explained packet is exactly what you need to learn more about this, there are some great advantages of it, and how it will work. Overall you’re learning about another language, which could end up becoming important in the near future.

Introducing Swift

We have addressed that it is a programming language, but what more is there to it. Well it is a multi-paradigm generic purpose, programming language compiled. It was developed by Apple Inc. 5 years ago. It was used for z/OS, Linux, tvOS, watchOS, macOS, iPadOS, and iOS,. So as you can see you’ve been amongst it for quite a while now. This was also planned to work with Cocoa Touch frameworks and Apple’s Cocoa. Also this is an open source framework as well.

On this you will be able to find a number of features on it, one of them is the closure support, which focuses on the parameter, and syntaxes. Then there is string support, access control, optionals and chaining, value types, protocol oriented programming. It also has libraries, runtime, and development. There are certain codes that are used to aid with development, and for various OS systems, like iOS7 there needs to be run-times allocated to it. Not to mention but there is also memory management, this allows for easier memory allocation and de-allocation. Debugging and other element are also present, this is one of the key features of the Swift system, it has the ability to be cleaned and run with no bugs making the properties of interactions increase. The performance is also another feature that has to be considered. They are known to have one of the most well know performance. So as you can see quite an array of features that are available for use.

Advantage and Drawbacks

You got the Swift programming language explained, now it’s time to look at how effective it is for apps. Once of the benefits of this is that there is a super open source community. Back in 2015 Apple announced that it was going to be open source, this is good because that there are a lot more chances to make it into a developer friendly programming language. There is easy code readability, it is actually one of the easiest to read and write, so this will allow you to work faster, and save your time, and use the time for any other things you have to do. Furthermore with the code being easy to maintain you don’t have to take time to sort files and such out, all of the content will be in one file, so easy to maintain. You can also expect a speedy app development. Swift is actually faster than any other language, it is 2.6 times faster than Objective C, so now you’ll have so much spare time.

However the language is still quite young, so there is not much experience with it or, people may not assume that it is mature enough to be used evidently. And there is a point because after all these years the first stable release was last year, so all the other times it failed. Also there is a limited talent pool, even though Swift is growing, the community however remains small compared to other open source languages. You should also expect a lack of support from the other earlier version of the iOS, because it has a hard time running on older versions. So these are some of the things that have to be endured. But in the near future Swift may end up taking over the world, you never know.

Learning Swift

If you’re interested in learning the language that’s great, you’re learning something new. So one of the ways to learn this is through apps, Apple actually has an app called Swift Playgrounds that you can get from the app store. On it there you will get an intro about the app development, and the basic fundamentals of it. They will also have reference guides and so on.

But if you don’t feel like learning it through there then you can choose from a number of courses that are available either online, or at some kind on institute. These courses will usually last about a month or a maximum of three, but if you’re learning more then it can be extended to 6 months. Another way to learn is though free online videos on YouTube(like this), there are some videos that provide you the entire 6 month course in a three hours video, this is a very cost effective method. Overall you want to choose something that will work for you if you’re interested in learning the language.
