Hi Vikrant,

A simple way to do this would be using prompt(), much like in the previous video:

const weather = prompt('What is the weather?');

With the code as written in the video the only acceptable answers will be 'sun', 'rain', or 'snow'. Otherwise the code will run the final else statement.

If you want to view the response outside the console you could replace console.log() with alert().

These methods work fine for testing but they aren't the most elegant ways for users to interact with a site. Stick with the courses and you'll learn more ways of receiving user inputs and displaying information, such as through text/dropdowns and changing HTML on the page with JavaScript. I hope this helps!

Thank you but how would we write the if else or it would be written still the same?

The logic stays the same so you wouldn't need to do anything besides swap out console.log() for alert(). All that you're doing is changing where the message is displayed. Like this:

const weather = prompt("What's the weather?");

if ( weather === 'sun' ) {
  alert("It's sunny, so I'm going swimming.");
} else if ( weather === 'rain' ) {
  alert("It's raining, so I will read a book.");
} else if ( weather === 'snow' ) {
  alert("It's snowing, so I'm going sledding.");
} else {
  alert("I don't know what I'm doing today.");
}

const weather = prompt("What's the weather?");

if ( weather.toUpperCase === 'sun' ) {
  alert("It's sunny, so I'm going swimming.");
} else if ( weather.toUpperCase === 'rain' ) {
  alert("It's raining, so I will read a book.");
} else if ( weather.toUpperCase === 'snow' ) {
  alert("It's snowing, so I'm going sledding.");
} else {
  alert("I don't know what I'm doing today.");
}

This will make sure that even if they type the weather in uppercase it will still give the expected behavior.
