React Js Check if Number is not Greater than 0
In this tutorial, we'll explore how to use React.js to check if a number is not greater than 0. We'll create a simple React application to demonstrate this concept.
To get started, let's examine the code snippet provided:

How to Use React js to Check if a Number is Not Greater than 0
xxxxxxxxxx <script type="text/babel"> function App() { const numberToCheck = -5; // Replace with your actual number return ( <div className="container"> <h3 className='title'>React Js Check if Number is not Greater than 0</h3> <p>Number : {numberToCheck}</p> {numberToCheck <= 0 ? 'The number is not greater than 0.' : 'The number is greater than 0.'} </div> ); } ReactDOM.render(<App />, document.getElementById("app")); </script>This code defines a React component called App. It sets the variable numberToCheck to 42, but you can replace it with any number you want to check. The component then renders this number along with a conditional message.
The heart of the conditional check lies in this part of the code:
xxxxxxxxxx {numberToCheck <= 0 ? 'The number is not greater than 0.' : 'The number is greater than 0.' }Here, we use a JSX expression within curly braces to check whether numberToCheck is less than or equal to 0. If it is, it displays the message "The number is not greater than 0." If it's greater than 0, it displays "The number is greater than 0."
Output of this Code is
xxxxxxxxxxReact Js Check if Number is not Greater than 0Number : -5The number is not greater than 0.If you replace it with const numberToCheck = 10;, the output will b
xxxxxxxxxxNumber : 10The number is greater than 0.
