The eval() function evaluates a string and executes it as if
it was script code.

In this example we use eval() on some strings and see what
it returns:

<script type="text/javascript">

eval("x=10;y=20;document.write(x*y)");
document.write("<br />");

document.write(eval("2+2"));
document.write("<br />");

var x=10;
document.write(eval(x+17));
document.write("<br />");

</script>

The output of the code above will be:

200
4
27
