Break Statement

Break statement is used to

• Terminate a case in a switch statement
• Terminate a loop on a conditional test

Break statement forces the loop to terminate and the control passes to the first statement after the loop.

Let us see a switch-case program.

function alphabetCount(alphabet) {
	switch (alphabet) {
	case "a" :
		trace(alphabet+" is 1st alphabet.");
		break;
	case "b" :
		trace(alphabet+" is 2nd alphabet.");
		break;
	case "c" :
		trace(alphabet+" is 3rd alphabet.");
		break;
	case "d" :
		trace(alphabet+" is 4th alphabet.");
		break;
	case "e" :
		trace(alphabet+" is 5th alphabet.");
		break;
	case "f" :
		trace(alphabet+" is 6th alphabet.");
		break;
	case "g" :
		trace(alphabet+" is 7th alphabet.");
		break;
	case "h" :
		trace(alphabet+" is 8th alphabet.");
		break;
	case "i" :
		trace(alphabet+" is 9th alphabet.");
		break;
	case "j" :
		trace(alphabet+" is 10th alphabet.");
		break;
	case "k" :
		trace(alphabet+" is 11th alphabet.");
		break;
	case "l" :
		trace(alphabet+" is 12th alphabet.");
		break;
	case "m" :
		trace(alphabet+" is 13th alphabet.");
		break;
	case "n" :
		trace(alphabet+" is 14th alphabet.");
		break;
	case "o" :
		trace(alphabet+" is 15th alphabet.");
		break;
	case "p" :
		trace(alphabet+" is 16th alphabet.");
		break;
	case "q" :
		trace(alphabet+" is 17th alphabet.");
		break;
	case "r" :
		trace(alphabet+" is 18th alphabet.");
		break;
	case "s" :
		trace(alphabet+" is 19th alphabet.");
		break;
	case "t" :
		trace(alphabet+" is 20th alphabet.");
		break;
	case "u" :
		trace(alphabet+" is 21st alphabet.");
		break;
	case "v" :
		trace(alphabet+" is 22nd alphabet.");
		break;
	case "w" :
		trace(alphabet+" is 23rd alphabet.");
		break;
	case "x" :
		trace(alphabet+" is 24th alphabet.");
		break;
	case "y" :
		trace(alphabet+" is 25th alphabet.");
		break;
	case "z" :
		trace(alphabet+" is 26th alphabet.");
		break;
	default :
		trace("This is not an alphabet.");
		break;
	}
}
// This function call gives the following trace output.
// e is 5th alphabet.
alphabetCount("e");

Let us see a for loop.

var num = 10;
for (var i = 1; i<=100; i++) {
	trace("number: "+i);
	if (i == num) {
		break;
	}
}
// Above code produces following trace output 
// (only till i is equal to 10).
// number: 1
// number: 2
// number: 3
// number: 4
// number: 5
// number: 6
// number: 7
// number: 8
// number: 9
// number: 10
//
// As soon as i becomes equal to 10, break statement forces 
// the loop to terminate.
