Suppose we want to check a user's age, if the age is greater than or equal to 18 years old, the user is an adult, otherwise the user is not an adult. The code representation is as follows :

<script type="text/javascript">
   var myage = 18;
   if(myage>=18)   // myage>=18 is the judgment condition
    { document.write("You are an adult."); } 
   else   //Otherwise the age is less than 18
    { document.write("Under 18 years old, you Not an adult." ); }
 </script>
