How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Getting Started With React and TypeScript Pt.2

If you ever wanted to learn how to use React and TypeScript, you are on the right place. This tutorial will help you understand all types you can expect in TypeScript and how to work with them. Learn about these basic types so you can start using React and TypeScript today.

Getting Started With React and TypeScript Part 1.

Getting Started With React and TypeScript Part 3.

Getting Started With React and TypeScript Part 4.

Types

Before you start using React and TypeScript you should get familiar with types you can use in TypeScript. TypeScript supports all types that exist in JavaScript. On top of it, TypeScript adds some new types. Here is an overview of the types you can expect and use when you work with React and TypeScript together, or just with TypeScript.

Number

Like in JavaScript the number type represents both, integer and floating point numbers. In other words, there is no one specific type for integers and other for floats. Both are united under the same type, number. These numbers also include hexadecimal and decimal literals, and binary and octal literals introduced in ECMAScript 2015.

// The ': number' after variable name
// and before equal sign specifies number type
// Declare new variable of type number
let numberExample: number

// Assign a value to 'numberExample'
numberExample = 979

// Declare and initialize variable of type number
const numberInteger: number = 13 // number type is not necessary here due to type inference
const numberFloat: number = 8.12 // number type is not necessary here due to type inference
const numberHex: number = 0xf00d // number type is not necessary here due to type inference
const numberBinary: number = 0b111110111 // number type is not necessary here due to type inference
const numberOctal: number = 0o767 // number type is not necessary here due to type inference

BigInt

The BigInt type is a new type that was recently added to the JavaScript language specification. Why? In JavaScript, the number type cannot represent integer values larger than 2^53, or less than -2^53 for negatives. This means that you can work with numbers of up to around 16 decimal digits.

Sometimes, this may not be enough. You may need something that can handle numbers even bigger than that. In that case, you can use the new BigInt value. You can use the BigInt to represent a number of arbitrary value. When you want to create BigInt you do that by appending n to the end of the number.

When it comes to working with React and TypeScript, you will probably not need to use BigInt so often. Maybe never. Nonetheless, it is still good to know what it is.

// The ': bigint' after variable name
// and before equal sign specifies bigint type
// Declare new variable of type bigint
let bigIntExampleTwo: bigint

// Assign a value to 'bigIntExampleTwo'
bigIntExampleTwo = 987654321987654321987654321987654321000n

// Try to change the value of 'bigIntExampleTwo' to different type
bigIntExampleTwo = 159 // error: Type '159' is not assignable to type 'bigint'.

// Declare and initialize variable of type bigint
const bigIntExample: bigint = 1234567890123456789012345678901234567890n // bigint type is not necessary here due to type inference

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

• React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
• React.js and React Native have similar syntax and workflows, but their implementation is quite different.
• React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
• React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

* React.js Developer Salary by Country

• United States- $120,000
• Canada - $110,000
• United Kingdom - $71,820
• The Netherlands $49,095
• Spain - $35,423.00
• France - $44,284
• Ukraine - $28,990
• India - $9,843
• Sweden - $55,173
• Singapore - $43,801

In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.

However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.

It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.

As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.

How to Hire React.js Developers?

• Conduct thorough candidate research, including portfolios and areas of expertise.
• Before you sit down with your interviewing panel, do some homework.
• Examine the final outcome and hire the ideal candidate.

Why is React.js Popular?

React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.

Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.

Final thoughts:

As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.
