Do you want to explore the simple steps to use comments in react? If yes, go through this guide and get a better idea of this process. In general, ReactJS is the JavaScript library that is effectively useful for building user interfaces. It is component-based, declarative, and technology stack agnostic. It can be effectively designed for simplicity, scalability and speed.
Such features make it the most popular library among various web developers. Here in this guide, you can check out how to create the react application and add comments.
Creating React Application:
Follow the steps correctly and then explore the simple steps to use comments in react.
Step 1: Create the React application with the below-mentioned command:
npx create-react-app my-app
Step 2: Move to the project folder my-app with the below-mentioned command:
cd my-app
Step 3: Start the development server with the below-mentioned command:
yarn start
(It will run the application at localhost:3000, and here you can check out all the changes according to the application.)
Project Structure:
Example 1: Comments for React Components. You can write the comments in react using the asterisk format /* */ or the double forward-slash // as same as regular JavaScript.
| import React, { Component } from ‘react’;
// This is a comment class App extends Component { /* This is also a comment*/ render() { return ( <div> <h1>Welcome to GeeksforGeeks</h1> </div> ); } } export default App; |
Example 1: If you want to comment on things around the render block, then the example mentioned above will never work. It is mainly since you use JSX around the render block and have to use multi-line comment around the curly braces {/* */}.
| import React, { Component } from ‘react’;
class App extends Component { render() { return ( <div> // This is not a valid comment /* Neither is this */
{/* THIS ONE IS A VALID COMMENT */}
<h1>Welcome to GeeksforGeeks</h1> </div> ); } }
export default App; |
Note: Here, you have to remember that, even though JSX gets rendered similar to standard HTML. It is the syntax extension to JavaScript. Therefore using <!– –> as you are doing with XML and HTML will never work.
| import React, { Component } from ‘react’;
class App extends Component { render() { return ( <div> <!– This is not a valid comment –> {/* THIS ONE IS A VALID COMMENT */} <h1>Welcome to GeeksforGeeks</h1> </div> ); } } export default App; |
Impact of using comments:
Writing effective comments is the primary process to get the most effective coding. It can make everything simple to maintain, debug and then build over existing web applications. When the programmers complete the project, they can move on to the following tasks and forget all the code details they wrote.
During that time, programmers can use comments to explain the most challenging part of their code and describe their thinking. Comments let you come back and find out the code later. They can save time when you need to add more features, debug or develop existing code.
The react components are simple to understand the unique scenario, but that will not always be the case. Sometimes, the functionality and purpose of the component can be unclear. At that time, writing proper comments can help you explain the problematic code more.
Essential factors of ReactJS:
When you install an application in the ReactJS, generally, you don’t install your enhancement of React through all the details. It is because such data in ReactJS is possibly their only purpose of the test. You can’t often install just in the comment design without information.
Some information in your ReactJS test may be accurate when the users start to use the application. For instance, your comment may contain the table of good grade worth or actual department names.
To advance in the standard scenario, you’ll first configure the method of code migrations that adds into the ReactJS just the data you need in production. This insert method won’t add the comment test because it will work in the production later the initial code creates the production of ReactJS.
Get the first priority:
In earlier editions of code, before the migration process was released, it was general to insert the methods to add the test data because by each model during the installation, the ReactJS was entirely removed and re-created from scratch.
The task you downloaded utilizes the pre-migration way of containing entire data in the insertion way of an initializer class. You’ll disable the class of initializing and enable the migrations. After, you’ll update the insertion procedure in the migrations design class so that it adds the data only you need to be added in the production.
The application operates the ReactJS connection method and authentication structures to validate and allow the users. One of the pages is available only for administrators. Work the application and select the features of update credits from the menu below the courses.
Grab sufficient details:
Rather than manually removing the tested accounts, you’ll make a new ReactJS connection that has the only way for a user administrator account that you require in the production.
While you run the software, you don’t need to utilize the prod editions of the storage ReactJS files. It would be best if you used the dev editions. Therefore, you need to alter the ReactJS connection in the config file so the dev editions of the storage of ReactJSs.
Between these settings that should be altered are the ReactJS connection, but you’ll install those modifications afterwards while you generate a publish profile.
