React JS is an efficient, declarative JavaScript library for creating graphical user interfaces. It allows programmers to build complex GUIs from small and isolated code structures called components. The work of the components is to tell React JS what needs to be displayed on the screen. When the user changes data, React JS automatically updates and re-renders the components. To become a successful developer, you need to use appropriate tools to make your programs as efficient and effective as possible. That means creating interfaces that are intuitive and easy to navigate by users of all skill levels. And when it comes to developing graphical user interfaces, React JS is just the tool you need for the job. As a student of programming, therefore, this is one of the areas you need to work a little harder to not only graduate with a good grade but also gain the expertise required to compete with other app developers once you are out of college.

React JS uses JavaScript Extension (JSX) instead of regular JavaScript to create templates. JSX is an easy-to-use JavaScript syntax that enables users to create HTML quotes and use these quotes to render subcomponents. All websites contain HTML documents. The internet browser reads these documents and displays them as web pages on your computer or mobile device. This process gets the browser to create a document object model, showing how the web pages are organized. JSX allows developers to make modifications to document object models using a simple HTML-like code, which leads to significant improvement in the performance of the website. You can count on this platform to provide you with customized and meticulous solutions for your homework.

JSX (JavaScript Syntax Extension)

JavaScript Syntax Extension is a feature in React JS that is not necessary but recommended. React JS uses this feature for templating. JSX comes with several pros including:

It catches most errors during compilation
JSX is faster. It compiles the code in JavaScript while also performing optimization
If you are well-versed in HTML, you will find writing templates

JSX is similar to ordinary HTML in so many ways. However, there are a few conventions that you must take into account while using it.

Styling in React JS

In React JS, inline styling is recommended. The camelCase syntax is often used for this. Also, React JS automatically adds px after the number on particular elements. Remember that all the attribute names must be in camelCase. Instead of semi-colons, we use commas to differentiate declarations. This is because React's CSS values and attributes are stored in an object. You can add an inline style to any component in React. Other methods of styling in React JS are styled components and CSS modules.

Comments

Writing comments is a good practice in programming. When you want to write a comment in react, you must use curly brackets. The comments are often structured as shown below:

{// one-line comment...}

{/* multiple lines comment...*/}

Naming Convention

While HTML allows lowercase tag names, all components of React on the other hand must start uppercase letters. Also, instead of for and class, your XML attribute names should be htmlFor and ClassName. The “for” and “class” identifiers are discouraged because JSX is JavaScript.
