React.js is the most popular open-source front end JavaScript library for creating web applications. It is used for building User Interfaces specifically for single-page applications. It is used for handling the view layer for mobile and web applications. It also enables the developers to create reusable UI components and also large web applications that can modify the data without reloading the page. The primary aim of React is to be scalable, fast and simple. It only works on user interfaces in the application and corresponds to the view in the MVC template. It can also be used with other libraries of JavaScript and frameworks like AngularJS in MVC. ReactJS can also be written as React.js or simply React.
Scala is a functional, object-oriented programming language with a compact and succinct programming style. Scala is a programming language for constructing complex programmes that runs on the Java Virtual Machine (JVM). Scala has fewer lines of code than Java, is more type-safe, supports functional programming (FP), and excels at object-oriented programming (OOP). Designing and maintaining Scala-based applications are the main responsibilities of a Scala developer. They also take part in any architectural development efforts relating to the app.

An efficient Scala/React.js developer is supposed to perform certain roles and follow responsibilities to get the best results. React.js developers are responsible for developing and implementing components of user interface using React.js workflows and concepts such as Flux, Redux and Webpack. They are responsible for enhancing front end performance and also documenting the front-end code base. To be successful in Scala/React.js developer jobs, you need to have an in-depth knowledge of React and JavaScript concepts, exceptional front end coding skills along with an understanding of progressive web applications. He/she should also be able to design and build contemporary user interface components to improve performance of the application.
The technical and non-technical responsibilities a Scala/React.js developer job is supposed to follow are –

• Create the front-end features by leveraging the inbuilt React toolkit.
• Create reusable code for the prospects along with data visualization tools and libraries.
• Integrating wireframes and designs within the code of application.
• Keep an eye on interaction of users and convert them into useful information.
• Write the code of the application interface with JavaScript.
• Constantly monitor and enhance the application performance.
• Translate the wireframes and designs into high quality code.
• Continuously optimize the components to work smoothly across various devices and browsers.
• Develop an understanding of GIT, Sigma, CSS libraries, Adobe XD etc.
• Authentication of user information and developing responsive web-based user interface.
• Take responsibility for all architectural development efforts by writing app - specific code.
• Conduct a software evaluation.
• Make sure the application fits the specifications.
• Carry out regular debugging and testing of applications.
• Suggest any improvements to the application's methods and infrastructure promptly.
• Collaborate effectively across teams.
• Contribute to the team's performance improvement.
  The Scala/React.js developer’s job requires to be strongly proficient in object model, JavaScript, DOM manipulation, data structures, JSX, algorithms and Babel. He/she should also be able to write crisp and clear code based on best practices and guidelines.

If you are planning to get a Scala/React.js developer job, then you must be familiar with JavaScript. If not, this is the first step you should take and once you are familiar with JavaScript as a programming language, you need to go through frameworks and pick one for creating engaging web pages. You will come across Scala/React.js when you start selecting a JavaScript framework. A large percentage of the job openings for front end developers require experience in Scala/React.js. There are a lot of questions in this journey like what is Scala/React.js and how can you learn it. You can take online courses from several options available today and speed up your career. These courses will help you in understanding the beginner and advanced JavaScript topics to get familiar with React and Redux in order to build rich front-end applications. Apart from taking online courses, you can also go through the official React documentation which helps to understand the basic and advanced concepts along with keeping you up to date with the latest changes.
Let’s take a look at the methods and skills you will need to be proficient with to be successful in your Scala/React.js developer job –

In a Scala/React.js developer job, he/she should be eager to improve their knowledge of Facebook's most well-known JavaScript library. The following are some of the most important abilities required in a Scala/React.js developer job:

1. HTML+CSS

There is no single front-end developer who is unfamiliar with HTML and CSS. An organization should be able to work with these and craft user interfaces. The Scala/React.js developers should be able to –

• Work on and write semantic HTML tags.
• Write and work with CSS selectors.
• Implement a reset of CSS.
• Understand the flexbox and box model and reset to the border box.
• Implement responsive web principles along with use of media queries.

2. JSX

JSX is used to encapsulate the React.createElement() API. Without it, growing the API would be too tough, which is one of the reasons it's so important to the library and why the React team chose it in the first place. Theoretically, React.createElement() might be used to create a whole application. That would, however, be no quicker than using HTML directly. Although it may appear like incorporating our Markup into our template logic is a step backward, it just takes a few minutes using JSX to fall in love with the look.

3. Java and Python

Java is statically typed and compiled, whereas Python is dynamically typed and interpreted. Because of this one difference, Java is quicker at runtime and simpler to debug, but Python is easier to use and understand. Python's popularity stems in large part from its communicability; people just understand it better. It comes with a slew of Python libraries, so even the most inexperienced programmer won't have to start from scratch. Java has a vast number of libraries and a strong community since it is ancient and still widely used. As a Scala/React.js engineer, you should be well-versed in both languages.

4. Spark, Hadoop and MapReduce

You must be knowledgeable with Spark, Hadoop, and MapReduce in order to be successful in a Scala/React.js developer job. For years, Hadoop had been the undisputed king of big data, until Spark came along. Since its original release in 2014, Apache Spark has been sparking the world of big data. Because of its user-friendly APIs and expected speeds of up to 100 times faster than Hadoop MapReduce, some commentators believe Spark has marked the advent of a new era in big data.

5. ETL architecture

ETL plays a big role in the data integration process (extract, transform, and load). It's the backbone of today's business intelligence and analytics workloads, efficiently transporting and altering data from source to goal. Understanding how ETL works is one thing; creating a company-wide ETL infrastructure is quite another. Like real-world construction projects, ETL architecture necessitates a strategy and a solid foundation to guarantee that your process satisfies your present needs and expands with you as you grow.

You must devise an effective job-search strategy while gaining as much practical experience as possible. Consider what you're searching for and how you'll use that information to narrow down your search before you start looking for employment. It's all about getting your hands dirty and putting your abilities to work when it comes to demonstrating to employers that you're job-ready. As a result, it's critical to keep learning and improving. The more open source, volunteer, or freelancing projects you work on, the more you'll have to talk about in an interview.
