JavaScript Break and Continue

JavaScript break and continue statement/keyword is used to control the loop.

JavaScript break Statement

JavaScript break statement is used to exit from the loop when the required condition is met. Here is an example uses break statement to exit the loop:

<!DOCTYPE html>
<html>
<head>
	<title>JavaScript Break Statement</title>
</head>
<body>

<p>Loop breaks when i becomes equal to 5</p>
<p id="break_statement_para1"></p>
<script>
	var text = "";
	var i;
	for(i = 0; i < 10; i++)
	{
		if(i === 5)
		{
			break;
		}
		text += + i + "<br>";
	}
	document.getElementById("break_statement_para1").innerHTML = text;
</script>

</body>
</html>

Here is the output produced by the above JavaScript break statement example program.

Here is the live demo output of the above break keyword example in JavaScript.

Here is another example also demonstrates the use of break statement/keyword in JavaScript.

<!DOCTYPE HTML>
<HTML>
<HEAD>
	<TITLE>JavaScript Break Statement Example</TITLE>
</HEAD>
<BODY>

<SCRIPT type="text/javascript">
	var count=0;
	while(count<10)
	{
		++count;
		if((count%5==0))
			break;	
		else
			document.write("count="+count+"<BR/>");
	}
	document.write("The while loop exited.");
</SCRIPT>

</BODY>
</HTML>

Here is the output produced by the above break example in JavaScript.

JavaScript continue Statement

JavaScript continue statement is used to skip the remaining part of code and goes to the condition-checker part, if the required condition is met. Here is an example uses continue statement to skip one iteration of the loop:

<!DOCTYPE html>
<html>
<head>
	<title>JavaScript continue Statement Example</title>
</head>
<body>

<p>Loop breaks when i becomes equal to 5</p>
<p id="continue_statement_para1"></p>
<script>
	var text = "";
	var i;
	for(i = 0; i < 10; i++)
	{
		if(i === 5)
		{
			continue;
		}
		text += + i + "<br>";
	}
	document.getElementById("continue_statement_para1").innerHTML = text;
</script>

</body>
</html>

It will skip to print the value 5, so it will display the following result:

Here is another example also demonstrates continue statement in JavaScript.

<!DOCTYPE HTML>
<HTML>
<HEAD>
	<TITLE>JavaScript continue Statement Example</TITLE>
</HEAD>
<BODY>

<SCRIPT type="text/javascript">
	var count=0;
	while(count<10)
	{
		++count;
		if(count%2==0)
			continue;
		else
			document.write("count="+count+"<BR/>");
	}
	document.write("The while loop exited.");
</SCRIPT>

</BODY>
</HTML>

Here is the output of the above continue statement program in JavaScript.
