In this article I will explain about break and continue in JavaScript. This topic contains following sections

   1. Software requirement

   2. Prerequisite knowledge

   3. What is break statement?

   4. Example of break statement

Software requirement

Before you start reading this tutorial you should make sure that

   1. Windows any version is installed on your machine.

   2. Notepad or any text editor for writing code.

Prerequisite knowledge

Before you go ahead, it is required that you should have

   1. Basic knowledge of JavaScript.

   2. Basic knowledge of HTML.

   3. Knowledge of any programming language is an added advantage.

What is break statement?

Break statement exits the loop. Consider an example of a loop which contains 10 iterations. If on fifth iteration break statement encounters then rest of the iterations i.e. 6th to 10th will not happen and code execution after the loop will continue.

Example of break statement

Consider the code sample below

<script type="text/javascript">
 for (i = 0; i < 10; i++) {
    document.write(i);

    if (i == 5)
       break;
}
</script>

The output of this program is ‘012345’

What is continue statement

Continue statement jumps one iteration of the loop. Consider an example of a loop which contains 10 iterations. If on fifth iteration continue statement encounters then that iteration i.e. 5th skips and rest of the iterations i.e. 6th to 10th continue to execute.

Example of continue statement

Consider the code sample below

<script type="text/javascript">
        for (i = 0; i < 10; i++) {
            if (i == 5)
                continue;
        document.write(i);           
    }
</script>

The output of this program is ‘012346789’
