Where can I learn techniques to use less IF statements for JavaScript?

You can write if statement inline.

var a = 11; 
a == 10 ? alert("true") : alert("false");

Even more sophisticated

var isTen = (a == 10) ? "yes" : "no";

More generally, a good solution to deal with data and avoid loops is to use functional patterns, like filter or map/reduce functions. It is a bit tricky at the beginning but totally worth the effort. It really makes your code clearer.

Also the less known .some() and .every() are neat ways to test the content of your arrays efficiently.
