Advantages of JavaScript

Many if not most of its advantages take root in the way JavaScript is often used and run in the client’s browser directly. Yet there are a few other features resulting in the language’s advantages.

Speed

JavaScript is recognized as being very fast most of the time due to the abovementioned direct execution in a client’s browser. The major browsers also support JUT (just in time) compilation for JavaScript which takes away the need to compile the code before one runs it.

Simplicity

The structure of the language and its syntax stems from that of Java. This makes it one of the easier programming languages to learn if we take some other popular ones to compare.

Popularity

JavaScript is commonplace all over the web, and thanks to Node.js, it’s growing in popularity with the back-end developers, too. There is also an abundance of learning resources for JavaScript making it a go-to language for many.

Rich Interfaces

Giving the developers the opportunity to create features such as drag-and-drop or components like sliders, JavaScript will give your site enhanced UI and UX which is valued more and more by the clients.

Extended Functionality

A JavaScript developer can enhance a web page’s functionality through snippets of JavaScript written up for third-party extensions.

Interoperability

JavaScript can be placed into any web page which is a big advantage compared to many other scripting languages. The list of various applications JavaScript can be used in also runs long as other languages like Pearl and PHP support JavaScript.

With UI and UX becoming more and more important for users and hence, businesses, there are a few general trends that stand out in the way JavaScript and its use are developing.

TypeScript is one of JavaScript’s supersets that’s spiked in popularity over the past 10 years and even placed in the top 10 of RedMonk’s Top 20 Languages. Leading businesses in many industries are shifting to TypeScript and many more will join shortly.

JavaScript libraries are in great demand since these frameworks are the base of almost any web development project anywhere. So developers are always on the hunt for these tools. Libraries such as Vue, Angular and React are booming. Piggybacking off the previous point, it’s important to say that even though the competition is tough, JavaScript programmers are still giving their preference to ReactJS created by Facebook and used by some of the corp giants. This UI design library is a favorite when it comes to cross-platform apps and responsive single-page apps.

Perhaps the biggest trend related to JavaScript of them all is moving to web components and making them framework-independent. Web components need less runtime and are less and less reliant on JavaScript, hence more and more runnable across a variety of platforms.

In the light of web development leaning so eagerly towards JavaScript, let’s take a closer look at what JavaScript is actually good for and what one can build with it.  Thanks to Node.js, making a server with JavaScript has become so easy, that it could take just a few lines of code. Yet it leaves space for more complicated endeavors on the back-end, allowing for a sweet balance.

JavaScript has given us the drag-and-drop function in websites and while it’s quite obvious, we should still mention that this programming language is actively used in building growingly more robust web apps.

As we are watching mobile take over the lead of the web from desktop, it’s impossible to not mention JavaScript. It’s a dynamic and robust language that allows for mobile applications to be more engaging and responsive.

The latest trend here is building presentations in the form of websites. They are faster, smoother, they please the eye and they’re easy to make. Those who have tried are not likely to return to Powerpoint. As browser games became more complex and engaging with the addition of HTML5 canvas, this kind of online entertainment has become increasingly popular and continues growing in popularity and complexity all thanks to JavaScript.

JavaScript can be used to build hardware-controlling programs. LED lights, navigation devices, timers, buttons, levers and more, can be all controlled with a JavaScript program through a framework. This also is possible thanks to Node.js since it allows JavaScript developers to run programs outside the browser.

What about the skills a good JavaScript and full-stack developer should possess? Here are a few things to look for when you want to hire JavaScript developer.

Keeping up with times

A general rule for a professional in any industry is to be on top of the trends and happenings of said industry. This is especially valid for those in web development since IT is moving forward with the speed of sound. A good developer should know where to get his info fast, accurate and concise since time is one of the most valuable assets nowadays.

Good knowledge of different platforms/browsers and how each work

A savvy full-stack JavaScript developer will not only know how to build something in a particular environment but will also be able to tell how the software will behave in others. They would know if anything needs tweaking, changing or boosting for an app to run smoothly across platforms, browsers and devices.

React & Redux

This is more of a novelty skill JavaScript developers should be picking up. React – a JavaScript framework mentioned earlier – has taken a growth spur in popularity in the last 5 years and has become the flagship library used by JavaScript programmers.

HTML / CSS Frameworks

HTML and CSS lie at the core of front-end development and coding in general. A worthy full-stack developer will be familiar with the latest developments in features and functions of HTML5 and CSS3 and their behaviors when combined in different frameworks.

Version Control/Git

This is somewhat of a teamwork and leadership skill. When working on a project a JavaScript developer is most likely to work in a team with others like them – senior or junior, no matter – and one of the most important parts of the team’s work will be having all the versions of their work synced. Version control is essential when advancing in a career in development and technologies like GIT can be of immense help.

Front-End Frameworks

It’s important to build on the work already done and use the base to speed up the process and dedicate more time to more advanced features rather than the base that’s often the same for every project. Knowing front-end frameworks is incredibly valuable for a JavaScript developer.

Examples of Javascript interview questions

We’ve prepared a few example questions and expected answers for when you want to hire  JavaScript developer and are holding interviews. These will help you feel more confident if your decisions even if you’re not IT savvy.

Q1: What is JavaScript?

JavaScript is a scripting language that is used in both client-side and server-side development and can be inserted into HTML pages as web browsers can read and understand it. As a programming language JavaScript is Object-based.

Q2: Who (company) developed JavaScript?

JavaScript was developed by Netscape.

Q3: What name is JavaScript originally known under?

Marc Andreessen, the founder of Netscape, first called it Mocha. Fall of 1995 brought a name change and the language was dubbed LiveScript. Then shortly after, still in 1995, the name JavaScript was adopted.

Q4: Does JavaScript support automatic type conversion?

Yes. It is commonly used by JavaScript developers

Q5: What does NULL mean in Javascript?

The NULL value represents no value or no object. It implies no object or null string, no valid boolean value, no number and no array object.

Q6: Please explain the difference between let and var.

JavaScript developers use both JS keywords for variable and method declaration. The main difference, however, is that the ‘var’ is function scoped, while the ‘let’ is block scoped.

Q7: What is the meaning of deferred scripts in JavaScript?

When a page loads, there is a delay in displaying the page if the server is slow or the script that needs to load is bulky. This is because the parsing of the HTML code is paused for the time the script is executing.

The use of deferred scripts creates a delay in the script execution for the time the HTML parser is running and ultimately reduces the loading time of the webpage.

Q8: What is an argument object in JavaScript?

The variables of JavaScript represent the arguments that are passed to a function.

Q9: What is the difference between JavaScript and JScript?

While Netscape provides the JavaScript language, Microsoft provides the same thing but with a changed name to avoid any trademark issues. So in essence, they’re the same thing.

Q10: How does one write a comment in JavaScript?

Depends on the type of comment you want to write. There are two.

Single Line Comment: marked by // (double forward slash)

Multi-Line Comment: marked by a slash with asterisk symbol Ex.: /* comment here */
