What are the skills required for react native developer

 Front-end developers today rely on React to build their applications. Learning React improves your development skills, and many organizations consider them essential. 

In order to become proficient with Facebook's prominent JavaScript Library, React developers need to improve their skills or audit the material. 

Check your skills against these essential React skills.

1. A combination of HTML and CSS

HTML and CSS are familiar to most front-end developers. A company must be able to create user interfaces and work with them. 

A React developer must be able to:

Semantic HTML tags are written and worked with

Write CSS selectors and work with selectors

The CSS should be reset

Understanding and resetting the border-box model

Learn how to use flexbox

Use media queries properly and work with responsive web principles

2. JSX

HTML isn't really touched in React. As a React developer, you're working with JSX, one of the most amazing parts of your ecosystem. 

Because JSX looks so much like HTML you could consider it HTML-flavored JavaScript. 

With JSX, you understand how to work intuitively if you're familiar with HTML and CSS.

3. Fundamentals of JavaScript and ES6

If you want to rock React, you must be familiar with the JavaScript language's fundamentals, but these ES6 skills are also necessary: 

Scope and variables

You need to know when and where you can access the data you need. JavaScript provides us with the capability of storing data in memory and accessing it later on within our applications via variables. 

Methods for arrays

Arrays and objects are one thing; storing data and accessing it is another. Understanding and manipulating data is another. 

Every developer's toolbox should include JavaScript array methods. The most effective methods are *.map*, *.filter*, and *.reduce*.

Functionality and arrow functionality

Whenever you construct a component in React, it is in some way a function. The technical term for a class is a construction function. 

If you're creating a 'class component' or a 'functional component', it's a function instead of a class. 

Manipulating the DOM and handling events

DOM elements are rarely manipulated in React. Thanks to JSX, we now have an abstraction for DOM elements. 

In React, the native event object that you get when manipulating the DOM is wrapped up in the SyntheticEvent. 

"This" keyword

There are several common JavaScript features that are misused, including the ‘this’ keyword. 

The ‘this’ keyword acts as a pointer. When referencing an object, you can use the keyword 'this' to refer to it without knowing the name of that object.

Functions with higher-order parameters and callbacks

*Input/output, or input/output programming, is driven by the fact that functions can be passed around as arguments-in the case of high order functions and callbacks. 

Object creation and prototypal inheritance

Functional programming paradigms are well-suited to react in many aspects. Although, you work in a world of classes, which means you create objects. 

You will have a good understanding of how JavaScript's prototype chain works if you understand how inheritance works in JavaScript. 

You should also remember that JavaScript does not create traditional classes. Classes in JavaScript are simply syntactic sugar added to the object prototype chain. 

4. Git

Git is a must for developers who store their projects on services such as GitHub, Bitbucket, and GitLab. Skills that you should just have on hand at all times include:

Adding, committing, pushing, and pulling changes

Strategies for mergers and acquisitions

Managing merge conflicts
