s





Step 2: Create an Event Lister

Add an event steering elements to eache will update the gas price in real-time. What the event occurs, you willll update the ’valument attributes:


inputs.forEach(input => {

Step 3: Update Gass Value Function


Create a separate fuel to date updates the price value in real-time. This function with the new ofnawVale as an argument:
