How to concatenate unicode and variable in ReactJS ?

Unicode is an encoding standard for all characters in the universe. Every language code and symbol in this world is assigned by Unicode. There is no encoding standard that supports all languages, By using the Unicode standard, we can retrieve and combine data with all language combinations.

Example: 

U+2192

In the above example, a right-facing arrow is represented in Unicode by U+2192.

Prerequisites:

• NPM & Node.js
• React JS
• Unicode
• parseInt
• String.fromCodePoint

Approach:

• To concatenate Unicode and variables in React JS we will pass the unicode value as a prop to the App component. Then, first, convert Unicode into its numerical value, and for that, we will use parseInt.

parseInt(Unicode,base)

• Now, this numerical value needs to be converted into its character and for that, we can use

String.fromCodePoint(numericalValue).

Steps to Create React Application:

Step 1: Create a React application using the following command.

npx create-react-app geeksforgeeks

Step 2: After creating your project folder i.e. geeksforgeeks, move to it using the following command.

cd geeksforgeeks

Project Structure:

Folder structure

Example: This example implement the unicode concatemation with variable using the parseInt and fromCodePoint methods.

Step to Run the Application: run the local server using the following command within the react-app directory  

npm start

Output: This output will be visible on the http://localhost:3000 on the browser window.
