Can we use multiple else if

Question

var course = prompt ("Enter course number");
if (course == 1) {
document.write("<h1>HTML Tutorial</h1>");
} else if (course == 2) {
document.write("<h1>CSS Tutorial</h1>");
} else if (course == 3) {
document.write("<h1>JavaScript Tutorial</h1>");
} else {document.write ("No such course available");
}

Is this valid?

Hello, Manoj!
That's right, this is a valid action

Please see the lesson from SoloLearn to understand the whole concept of "conditions"

- if statements
- else if statements

Else statements 'cannot' be used infinitely.
Only ONE else statement are allowed for ONE if statement.
