Can anybody explain to me why my if statement doesn't work? I thought you could use an isNaN statement like this?

// Collect input from a user const num=parseFloat(prompt("Please provide a number")); if(isNaN === num){ console.log(This is not a number); } else{ // Convert the input to a number

// Use Math.random() and the user's number to generate a random number const random = Math.floor(Math.random()*num)+1;

// Create a message displaying the random number console.log(${random} is a number between 1 and ${num}); }

It looks like you're using "isNaN" as a value, but it's a function. The proper syntax to test a variable named "num" to see if it is not a number would be: isNaN(num)

Thank you, I'm so embarrassed.
