What's app only on laptop without smartphone possible?

Since I do not have a smartphone, I've heard that I can use What's app on the computer. Is this really possible? Can I download the app to my laptop even if I do not have a smartphone and still use what's app normally?

The whole thing is called WhatsApp Web. As far as I know, this is not possible without a mobile phone, because you need a phone. On your phone, open WhatsApp and go to Settings on WhatsApp Web. There you have to take a picture of the code from your screen and make a connection.

That's fine. I was about half a year ago broken the phone, but needed What's app for work, then downloaded it on the laptop and used easily, but you need a mobile number for it once. Your contacts must also find you on What's app, that's only possible with your name

You can use an Android emulator and a landline number / mobile number (key mobile phone). Then confirm the code by call.

That's not what's being asked.
