Playing with ramda

functional.js

// Functional
var log = function(tag,val) { console.log(tag, val); return val; }
var isLightBackground = function(color) {
	// 765 - max distance
	log("color:",color);
	return log("result:", log("distance:", xcolor.distance(color, 'white')) < (765/2));
};

original.js

// Original
// Function determines is background light enough to show dark logo.
var isLightBackground = function(color) {
	// 765 - max distance
	return xcolor.distance(color, 'white') < (765/2);
};
// The task is to add some logs to see what are results getting returned

ramda.js

var R = require('ramda');
var log = R.curry(function(tag,val) { console.log(tag, val); return val; });
var distanceFromWhiteColor = R.flip(x.color.distance)('white');
var isLightDistance = R.lt(765/2);

var isLightBackground = R.compose(log("result:"), isLighterDistance, log("distance:"), distanceFromWhiteColor, log("color:"));

traditional.js

var isLightBackground = function(color) {
	console.log("color:", color);
	
	var distance = xcolor.distance(color, 'white');
	console.log("distance:", distance);
	
	// 765 - max distance
	var isLight = distance < (765/2));
	console.log("result:", isLight);
  return isLight;
};
