How to compare emails in javascript? - asp.net-mvc

Question

I am trying to make an edit profile page in which user can update its current email or pwd by inputting current email and password and then give new ones. I am also sending whole data of user(including username and password) when he sign in through viewdata.
#{
var user = (User)ViewData["User"];
}
<div class="account-info mt-3">
<fieldset class="border border-dark p-3">
<legend class="float-none w-auto">Account Info</legend>
<div class="mb-3 simpleinfo">
<label for="email" class="form-label">Enter Your Current Email</label>
<input type="email" class="form-control" name="Username" id="prevemail"/>
</div>
<div class="mb-3 simpleinfo">
<label for="prevpwd" class="form-label">Enter Your Current Password</label>
<input type="password" class="form-control" name="Pwd" id="prevpwd"/>
<button type="button" class="btn btn-success mt-4 checkcred">Update Credentials</button>
</div>
<div class="mb-3 simpleinfo">
<label for="email" class="form-label">Enter new Email</label>
<input asp-for="Username" disabled type="email" class="form-control" id="newemail">
</div>
<div class="mb-3 simpleinfo">
<label for="newpwd" class="form-label">Enter New Password</label>
<input type="password" disabled class="form-control" asp-for="Password" id="newpwd">
</div>
</fieldset>
</div>
Now i want to compare the email that user enters and the email that is present in the user object.
here's my code for this:
<script>
$('.checkcred').click(function() {
var prevemail = $('#prevemail').val();
var prevpassword=$('#prevpwd').val();
if(prevemail==#user.Username&&prevpassword==#user.Password)
{
alert("Validated");
}
else
{
alert("not validated");
}
});
</script>
But it is giving me syntax error on Console: Invalid or unexpected token.
Please lemme know what i am doing wrong.
