Switch statement
- In JavaScript, the switch statement is a control structure that allows to execution of different blocks of code based on the value of an expression.
- It is commonly used when you have multiple possible conditions to test against a single value.
Syntax:
switch (expression) {
case value1:
break;
case value2:
break;
// Add more cases as needed
default:
}
Example:
<!DOCTYPE html>
<html>
<body>
<script>
var grade = 'B';
var result;
switch (grade) {
case 'A':
result = "A Grade";
break;
case 'B':
result = "B Grade";
break;
case 'C':
result = "C Grade";
break;
default:
result = "No Grade";
}
document.write(result);
</script>
</body>
</html>
Output:
B Grade
