What are Prototypes in JavaScript? — JavaScript Interview Series

Prototypes. One of the most important topics in JavaScript and one that is regularly visited in JavaScript interviews. In this article, we will study prototypes in detail. So, let’s get started.

Let’s speak of an analogy before we dive deep into the concept of prototypes in JavaScript.

Every year, industries come up with new products which do not reach the consumer’s table. However, some of the outstanding features become parts of the upcoming products that the company releases. Hence, you can assume that the unreleased products serve as a prototype to the released products.

Now that you get the idea, time to dive in deep.

What are Objects in JavaScript?

Objects marry state and behavior into one entity. JavaScript is full of objects, for example, Array, String, and functions too are considered objects. Let’s consider the Array object. It has in-built methods such as pop() , push() , length(), etc .

When we define an ‘array’ here, we see that it automatically inherits the methods push(), length, pop(). Well, this is because of _prototypes. _Tada!

By definition, “In JavaScript, every object holds a reference to a superior object from which it inherits its properties. This superior object is called a prototype and this behavior is referred to as prototypal inheritance. The prototypal inheritance happens via a prototype chain.”

#MyStartInTech: An Interview With Juan Pablo Flores, PM at GitHub

The tech workforce in the US is not growing at an optimal pace. The number of schools offering computer science is not enough which is impacting the access of computer science to young women and students from marginalized communities.

The truth is that there are over  410,020 open computing jobs in the US but only  71,226 computer science students graduated into the tech workforce last year.

This is because only  47% of public high schools in the US offer computer science which deeply impacts its access to young women and students from marginalized communities.

To address this pressing issue, we have launched #MyStartInTech, a campaign dedicated to drawing attention to this cause and in turn, help widen access to computer science in schools. Learn more about the campaign by visiting  www.startin.tech

As part of this campaign, we present the #MyStartInTech interview series where some of the esteemed tech entrepreneurs and professionals in the industry share details about their journey in tech. With this, we hope to draw attention to the infinite opportunities that will lay open if young women and students are given the opportunity to study computer science.

In this interview, Juan Pablo Flores, Program Manager, GitHub talks about how he got his start in the tech world.

Juan Pablo is a computer engineer who has dived into the world of management. He is a Program Manager at the GitHub Education Team, where he supports student leaders to build and grow local technical communities in their schools in the GitHub Campus Experts Program.

Let’s find out what he has to say!

From Music to Web Development -My Path

From being a musician of a symphony orchestra to a web developer.

Since I was a child, my parents focused on cultivating my music literacy. My father is a famous musician and my mother is a doctor. Yes, I am also talented, my ears are born with absolute hearing. I can tell the exact pitch with closed eyes when people press any key on the piano. It would make sense that music should be my future career, right?

Going to a foreign country to continue music studies

After high school, I was admitted to the Shanghai Conservatory of Music where I studied hard for 4 years to obtain a diploma. In the second week, after receiving the certificate, I decided to visit Vienna, the famous city of music in Austria, because I didn’t want to stay at home for a career under the cover of my parents like a child forever. So I packed my bags and boarded a plane.

In Vienna, I passed the entrance exams to get into a Master’s course. “Don’t be idle anyway and give it a try” I thought. I signed up and came to the examination room. The result was very pleasant, I didn’t speak a word of German but I was admitted. Yes, I was proud of myself.

The studying journey in Vienna allowed me to make many friends, speak German fluently, co-operate with orchestras, whom I often performed with abroad. It was around the time I was about to graduate, that I met my husband.

The world is sometimes so wonderful. On the night of our wedding, I had to perform in the world-famous Golden Hall in Vienna. It was so stressful that after our concert and dinner I fell asleep while walking.

"Akka Serverless Is Really The First Of Its Kind"

We chatted with Jonas Bonér, CEO and Founder of Lightbend about Akka Serverless and what makes it so different from other architectures. Jonas explains how data is kept secure in Akka Serverless and what limitations it removes with its data-centric backend application architecture.

JAXenter: Hi Jonas, thanks for the interview. Right out of the gate, let’s talk about Akka Serverless. What makes this new architecture so different?

Jonas Bonér: Akka Serverless is really the first of its kind. A lot of energy has gone into abstracting away the underlying infrastructure of the cloud with technologies such as Kubernetes and that has moved the industry forward significantly. But building high-performance, highly scalable, and resilient back-end services, and APIs takes a lot of specialized expertise – distributed computing is hard, even in a containerized world.

Akka Serverless abstracts away all of the hard stuff required to build this class of services – including databases, caches, and message brokers – allowing the developer to focus where there is the biggest value: the business logic.

**SEE ALSO: **“Cloud moved decision-making responsibility out of finance and into engineering”

JAXenter: How is data kept secure in Akka Serverless?

Jonas Bonér: Data is an incredibly important asset for any company, so we’ve spent a great deal of time coming up with a proper architecture that makes Akka Serverless as secure as possible.

Each project that developers create on Akka Serverless gets a unique scope. Within that scope, we make sure that incoming traffic is limited to only those services that developers have exposed to the outside world. From our “front door” to the pods running the services, all data is secured with mTLS connections. The data that we store is encrypted using AES256.

JAXenter: What are some of the biggest challenges organizations face in regards to serverless?

Jonas Bonér: The move to the cloud to date has primarily been about two things: infrastructure optimization and the adoption of SaaS applications. The next quantum leap of value generated by the cloud will come when serverless is able to address the full gamut of applications required to run a business.

But serverless today has been limited in applicability due to challenges related to performance, the management of state at scale, and the architectural complexity of building real-time systems with a serverless paradigm. But that is changing fast. We anticipate massive disruption to the status quo with entire swaths of today’s software infrastructure becoming abstracted by high-value stateful serverless offerings like Akka Serverless.
