Remove a character "~" from URL in jquery

Question

I am redirecting to a specific page after button click in jquery ajax success function

I have this code with me:

$.ajax({
   // additional code omitted
   success:function(data) {
         var value = JSON.parse(data.d);
        window.location.href = "https://www.example.com" + value.dataSet.Table[0].RedirectURL;
        }  
 });

Now I am getting value of value.dataSet.Table[0].RedirectURL as "~/myPost.aspx"

So the complete url becomes : https://www.example.com/~/myPost.aspx

To avoid this I had done something like this:

var url = "https://www.example.com" + "~/myPost.aspx"
window.location.href= url.replace("~","");

But this code doesn't redirect me to new page. It stays where it is.

What should be done to remove the tilde sign (~) from the URL such that it becomes like https://www.example.com/myPost.aspx Jquery Ajax?

EDIT:

My second attempt:

I have tried to remove the first character as I have ~ only at the beginning of the URL.

    function removeChar(str) {
        let temp = str.split('');
        return temp.slice(1).join('');
    }

and then...

    $.ajax({
   // additional code omitted
   success:function(data) {
         var value = JSON.parse(data.d);
        let inputURL = value.dataSet.Table[0].RedirectURL;
        let outputURL = removeChar(inputURL); // this gets /myPost.aspx but it doesn't redirect after this line.
        window.location.href = "http://www.example.com/" + outputURL;
     }  
 });

Note: The value of ** value.dataSet.Table[0].RedirectURL** is ~/myPost.aspx

In this case, it is not redirecting to the desired page. The page reloads and stays where it is.
