Syntax of if else statement:
if (condition) {
statements1;
}
else if (condition) {

}
else if (condition) {
statements3;
}
else{
statements4;
}
Example:
Below is an example of if else statement:
<script language="JavaScript" type="text/javascript">
var age = eval(prompt("How much you scored?", ""));
if (age >= 60) {
alert("First Division");
}
else if (age > 50 && age < 60) {
alert("Second Division");
}
else if (age >= 30 && age < 50) {
alert("Third Division");
}
else {
alert("Fail");
}
</script>
