Comments

Comments provide a way to document your programs so that other people can figure out what you did. There are two kinds of comments in ECMA Script. If you place two forward slashes in a row (//) they and everything to the end of that line are considered to be a comment. If you want a multi-line comment, start with /* and end with */ as shown here:

var interest;   // this is accumulated on a daily basis
var rate;       // expressed as a decimal; 75% is a rate of 0.75

/* Figure out the payment amount given a principal
   of $10,000 and 180 monthly payments. */
