// running .each() on a jQuery search executes the included function
// individually for each element it finds that matches the search
// (e.g. in this case, it runs the function redBorder() for each ‘a’
// tag). the parameter name ‘e’ refers to the found element
//
// j(‘a’).each(function() { redBorder(this); });
// this line sets up a continuous search for new elements on the
// page that might get inserted later. so, in this example, any
// HTML with an ‘a’ tag that gets inserted *after* the page loads
// will call redBorder() for each one in turn. this way you can
// catch and change anything that happens after the page load
// (e.g. a new news feed story on the Facebook newsfeed0
//ready(‘a’, function(e) { redBorder(e); });
ready(‘p’, myBackground);
//ready(‘p.byline’, myPfont);
ready(‘img’, hideImage);

//var xi = (‘h2:contains(Xi)’)
// this function could do anything with the results it receives
// ‘jnode’ refers to the jquery object the initial jQuery search
// found, so we refer to it and then continue on with familiar
// jQuery statements

So for my ERASE project I decided to go onto coin market cap and erase the numbers attached to coins. I thought this was a fun way to manipulate the market, I think rather than erasing replacing numbers could be a lot of fun too.
