JavaScript Dynamic Choice of Colors

I have a leaflet map and I want to assign colors to each "feature." The number of features can be different depending on changing geojson data. I am guessing there is some algorithm to do this.

Here is the code: (on each feature I would like to set the color to be different not the given color, because the data doesn't have a color)

var geomap = L.geoJson(geojson, {
            //TODO: change the colors to be randomly separated and updated based on the # of features
            //TODO: Should change the feature properties to be the population and zone number -- show this in the pop-up instead of the "description"
            style: function (feature) {
                return {color: feature.properties.color};
            },
            onEachFeature: function (feature, layer) {
                layer.bindPopup(feature.properties.zone);
            }
        });

So if I have 5 or 100 features I want to have different colors for each. Any hints or algorithms? This is in JavaScript obviously.

What is the difference between (null != someVariable) and (someVariable != null)? I have seen a lot of people using 'null' first in the comparison. Which one is better than the other and why?
