Hello guys, Today i will be teaching you some basic of JS breaks.


Ok let get started; JS is a short name for JavaScript. Break mean a statement that jump out of a loop also, continue statement jump over iteration in the loop.




For this example i will be using JS Switch() to jump out of a switch statement. If you don't know what Js Switch is please refer to this link.


Java Switch()

http://www.w3schools.com/js/js_switch.asp


What this script does breaks the loop and continues executing the code after the loop If there any.


Break Statement:

for (i=0;i<10;i++) {
if (i==3) { break;
}
x=x + "My Number is:" + i +"<br>";
}


Output:


My number is 0
My number is 1
My number is 2


Now we going to more on to continue statement. What this does is break iteration (in the loop), if a specified condition occurs, and continues with the next iteration in the loop.

What this example does is skip the value of 3


for (i=0;i<=10;i++){
if (i==3) continue;
x=x + "My Number is:" + i + "<br>";
}



Output:

My number is 0
My number is 1
My number is 2
My number is 4
My number is 5
My number is 6
My number is 7
My number is 8
My number is 9



JavaScript Labels:

Here another example of Java Labels. What this does is jump out of any JavaScript code block.


Example:


animals=["Dog","Cat","Rat","Mouse"];
list:
{
document.write(animals[0] + "<br>";
document.write(animals1] + "<br>";
document.write(animals[2] + "<br>";
break list;
document.write(animals[3] + "<br>";
document.write(animals[4] + "<br>";
document.write(animals[5] + "<br>";
}


Output:

Dog
Cat
Rat
Mouse
