Javascript: if-else-if-else ladder

In my previous post, I explained about if statement, if-else statement. In addition to these, Javascript provides if-else if- else ladder, used to choose a solution, when you had multiple alternatives.

Syntax
if(condition){
         //Block of statements
}else if(condition){
         //Block of statements
}else{
         //Block of statements
}

<body>
    <script type="text/javascript">
        var marks = prompt("Enter Your marks", 100);

        if (marks < 35) {
            document.write("You are failed");
        } else if (marks < 50) {
            document.write("You are passed and got third class");
        } else if (marks < 60) {
            document.write("You are passed and got second class");
        } else if (marks < 70) {
            document.write("You are passed and got first class");
        } else {
            document.write("You are passed and got distinction");
        }
    </script>
