what happens here how does it recieve data from a client. Is it simlar to an async function?

app.post("/Data",(req,res) =>{//function here somewhere
                    
                        
                        person.fname=req.body.name1;
                        person.lname=req.body.name2;
                        person.email=req.body.email;
                        person.passwrd=req.body.psswrd;
                        person.Type=req.body.type;
                        let s=false;
                        
                    });

I was thinking of something like this

app.post("/Data",async function front(req,res){//function here somewhere
                    
                        
                        person.fname=await req.body.name1;
                        person.lname=await req.body.name2;
                        person.email=await req.body.email;
                        person.passwrd=await req.body.psswrd;
                        person.Type=await req.body.type;
                        let s=false;
                        
                    });


//Then call the front() in another async which connects to a db collection like this await front()

Will this work? I have problems readind from the front and sellecting the collection. The collection is a radio button selected on the client side and it has to be changed from and to on the server side. So how does the app.post handle data?
