Follow below process to accomplish:

Step 1: Declare variable as public and static in code-behind file

C#

public partial class Page1 : System.Web.UI
{
   public string firstName = "Manas";
   
   protected void Page_Load()
   {
     // Your logic
   }
}

Step 2: Access the variable in js file:

JavaScript

<script>
    GetMyName();

    function GetMyName()
    {
	     alert(<%=this.firstName%>);
    }
</script>

Edit(Another way):

C#

public partial class Page1 : System.Web.UI
{
   public string firstName = "Manas";
   
   protected void Page_Load()
   {
     // Your logic
     string script = string.Format("var firstName = '{0}';", "Manas");
     if (!ClientScript.IsClientScriptBlockRegistered("myScript"))
     {
         ClientScript.RegisterClientScriptBlock(this.GetType(), "myScript", script, true);
     }
   }
}

Add code in temp.js file

JavaScript

<script>
    GetMyName();

    function GetMyName()
    {
	alert(firstName);
    }
</script>
