 <p>When something goes <em>wrong</em> in a piece of JavaScript code, the program will exit, most likely leaving the user in a confused state. For example, if you try to access a variable that doesn't exist: <code>Seed.print(asdf);</code> Seed will exit with the message: <code>ReferenceError Can't find variable: asdf</code>. It is possible to catch this sort of error, or exception, inside of your JavaScript program, ensuring that it doesn't terminate your program - or that if it does, it prints a useful error message. The <code>try/catch</code> construct provides a way to <em>try</em> to execute a segment of JavaScript, and, if it fails, run a second segment, without exiting the program. The second segment could print a user-friendly error message, ignore the exception entirely, or try to work around the problem. A quick example of <code>try/catch</code>:</p>
 <pre class="sh_javascript">
-try
-{
+try{
     Seed.print(asdf);
 }
-catch(e)
-{
+catch(e){
     Seed.print("Something went wrong!");
 }
 </pre>
 <p>It's also possible to determine what, exactly, went wrong. The '<code>e</code>' in the <code>catch</code> statement (which, by the way, you <em>cannot</em> omit) is actually an object containing information about the exception! We can access some of the basic properties of this object:</p>
 <pre class="sh_javascript">
-try
-{
+try{
     Seed.print(asdf);
 }
-catch(e)
-{
+catch(e){
     Seed.print("Something went wrong!");
