Just tried to subtitute console.log object with mine. This still first snippet version, so any suggestion, good critics, idea will be good and be heared :D. Thanks

evlog.js

	var evLog = {
		d: function(param){
			var bCheck = $('body').children('#playground').length;
			if(bCheck == 0){
				console.log("playground not found");
				var createDiv = document.createElement("div");
				createDiv.setAttribute("id", "playground");
				document.body.appendChild(createDiv);
			}

			var strBuilder;
			strBuilder = "<code id='evcode'>" + param + "</code>";
			document.getElementById("playground").innerHTML = strBuilder;
			//console.log(strBuilder);	

			var codeStyle = document.getElementById('evcode'),
				css = {
					color: '#a0294c',
					fontSize: '30px'
				};

			for(i in css){
				codeStyle.style[i] = css[i];
			}				

		}
	}

	//test
	evLog.d(1+1);
	evLog.d('yeahhhh');
