5 Tips To Become Better JavaScript Developer!

JavaScript is still a mystery to a lot of people. With it’s growing popularity with things like Node.js, Angular.js, and jQuery, people are wanting to know more and more about the language

With more beginners jumping in, there’s room to make mistakes that JavaScript will more than willing let you do. Right now, JavaScript is being bombarded with new frameworks and libraries that completely change our regular workflow. In this article we have listed 5 simple and quick JavaScript tips that will help beginners improve their code quality.

1.Work on API for security

Beginners often think that hiding elements from user using JavaScript is security but you should rather focus on your lack of obedience, that will make you a better coder. It’s always best to work with API layer so it will help you put up real security walls. API checks everything that passes through it. So API can prevent access to the unauthenticated call.

API should strictly not produce any information that user doesn't have the permission to access. It is best to build your own API with multiple layers of protection. JavaScript doesn't automatically hide and mask things.

2.Use Strict mode while writing the code

Strict mode was introduced in ECMA 5. It allows you to put a function or an entire script into strict operating context. It eliminates some of the silent JavaScript errors by throwing the errors explicitly. It is capable to throw exceptions when relatively unsafe actions take place. And sometimes strict mode code can run faster than non strict mode code. As currently all the major browsers support this feature you should start using strict mode.

3.Write easy to understand code

You must not write a confusing code, it will just make things worse. You should avoid the shortcuts while writing the code. A function like ShoeBox(); can be represented as ShBx(); but, that is not easy to understand. It is necessary to write the code as if you are writing the story in normal language. This approach really helps while debugging and beta testing.

Beginners often focus on number of lines and speed of coding. But to be fair, in the end, whether the app works flawlessly or it is buggy is all that matters. Number of lines of codes and efficiency of the app, both things are totally irrelevant.

4. Cache the length while looping

Beginners often forget this while writing a code and then end up debugging the thousands of lines of codes. While looping through a JavaScript array you can cache the length so that the overall performance is better. Be careful while creating an inner loop. You need to name the length variable differently in the inner one.

5.Test

To improve your confidence that code will behave as expected, write unit tests using a framework such as Jasmine or QUnit for each of your functions, using both expected and unexpected input parameters.

Run these tests in multiple browsers across multiple operating systems. if your code is stored in GitHub, you can take advantage of BrowserSwarm, a tool that automatically runs your unit tests when you commit your code

Eclipse, NetBeans or IntelliJ: Which is the best Java IDE?

Eclipse’s Luna release brought a range of
interesting new functions –– but how does
the Java IDE stand up to rivals NetBeans
and IntelliJ?
..

For quite some time now, Eclipse has had a thorn in its IDE.
With NetBeans and IntelliJ ever at its heels, the Eclipse
development environment has been battling to hold sway
over the Java community. It’s about time we compared the
big three in Java IDEs.

Over on JAXenter.de , the German Java community has voted
on how Eclipse stands up against the competition. Only 21%
of developers believed the Luna release has re-established
Eclipse as the best Java IDE in the world. And just over a
quarter of participants (26%) would say that Eclipse and its
competitors are generally the same, and that each software
has its own advantages and disadvantages.
Like in the Windows vs Mac vs Linux debate, it seems that
most devs have picked one IDE and are sticking firmly to it.
The results make it pretty clear that Eclipse’s Luna hasn’t
quite won back the entire Java community.

Eclipse: More than an IDE

While IntelliJ IDEA had already long since delivered support
for Java 8 (albeit slightly rudimentary), Eclipse struggled to
catch up with Java 8 support for its much-awaited Luna
release . On top of its new Java 8 features, Luna blinged out
with a brand new ‘Dark Theme’ which lets users change the
IDE’s background hue – but that’s also nothing that would
impress anyone working with NetBeans and IntelliJ IDEA.
The latest update has brought Eclipse up to an impressive
76 individual projects – from software modelling to IoT tools
and even runtime projects. Beating that in mind, you might
say Eclipse is less of an IDE and more of a technology
platform and open source community.
Being slow off the mark to adopt Java 8 functions is
relatively insignificant when compared with rough times
Eclipse had with the infamous Juno release and its frustrated
users. In spite of these troubles, Eclipse makes up for its
vices with a vibrant community of developers and a wide
range of plugins.

IntelliJ IDEA and NetBeans

In contrast to Eclipse, there’s no doubt about what exactly
IntelliJ IDEA does. Since it’s developed by one single
company (JetBrains), there’s somewhat less community
participation. But that also means that its built-in features
are far more cohesive. Eclipse can easily become confusing
with its endless plugins built by various community
members. IntelliJ IDEA could add a further feather to its cap
when Google selected it as the basis for Android Studio – the
new development environment for Android.

Right in middle, between Eclipse and IntelliJ IDEA, is
NetBeans. Previously part of the Sun development
environment, NetBeans slipped into the hands of Oracle, but
has managed to hold onto its faithful community. NetBeans
features platform functions for various extensions, and yet it
still provides a clearly framed functionality. The software
also has a head start on other IDEs with its JavaFX and
HTML5 features.

Each to their own IDE
When it comes to Java IDEs, developers are spoiled for
choice. Three free services battling each other to provide the
best functions and services – it’s something that other tech
communities can only dream of.
Like ninjas vs pirates, deciding on the world’s best Java IDE
is purely subjective – it all depends on what you need. A
swashbuckling, if sometimes chaotic, collection of plugins or
a stealthily integrated functionality?

ACCESS BLOCKED SITES

ACCESS BLOCKED SITES

It has been a long time ago that in colleges ,schools ,universities and offices that some websites are being blocked for use due to some security issues or because of pornography and social network over crowd.

Now the time had risen up to come over these limitations by some software's or by some tricks.

So that one can easily access the sites whenever he wants and whatever he want to browse or download too.

There are many methods available in tech world by which one can browse the blocked sites .

1. SOFTWARES
   Many softwares are available in third party software distributors market by which blocked sites can be accessed easily in which some main softwares are BLOCKED SITE ACCESSOR  ,HOTSPOT SHIELD,HOLA.
2. EXTENSIONS
   Many extensions do the same job and some known ones are STEALTHY ,FOX PROXY,FRIGATE .These extensions need to be installed on your browser i had my self checked them to work in GOOGLE CHROME.
3. MANUAL PROXY CHANGE
   Browse the GOOGLE and see a list of proxies of different countries ,note them down and write them accordingly in your browser proxy settings.Restart your browser and you are done with your proxy change and access your favorite sites.
   

NOW USE ANY OF THE ABOVE METHODS AND YOU CAN EASILY BROWSE THE BLOCKED SITES IN YOUR INSTITUTION .

I MYSELF PREFER TO USE THE SOFTWARE ONE AND THE EXTENSION ONE BECAUSE IN A SINGLE CLICK OR A KEYBOARD SHORTCUT YOU CAN CLOSE OR OPEN THEM WHEN YOU DON'T NEED THEM TO WORK AS YOU WILL BE EITHER IN HOME OR YOU WANT TO BROWSE THE SITES THAT ARE NOT BLOCKED AT ALL.
