## The `case` keywordEdit

The `case` keyword is used in the switch statement that is an alternative for complex `if … else if … else` statements.

### ExamplesEdit

The code

```
var array = [2, 3, 5, 7, 10, 11];
for (var i = 0; i < array.length; i++) {
switch (array[i]) {
case 0:
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:
case 8:
case 9:
alert(array[i] + " is a number with one digit.");
break;
default:
alert(array[i] + " is a number with several digits.");
break;
}
}
```

returns the following:

2 is a number with one digit. 3 is a number with one digit. 5 is a number with one digit. 7 is a number with one digit. 10 is a number with several digit. 11 is a number with several digit.
