Making a jQuery plugin

In this tutorial, we will see how to make a jquery plugin. First step is to create a self executing function. Inside this function we will create our own functions e.g. if we want to create a function then we should pass the jquery object to the self executing function to define a function just add property of the $.fn object e.g if the function name is test the definition should be $.fn.test = function(<optional_parameters>) {}; To call the function, just use $("selector").test();

In this tutorial, we will see how to make a chess borad (8 * 8),
First step is to print the board and then place the correct animals in the correct positions.
1.$.fn.board - In this method, we make the design of the board using javascript ECMA script 6
2.$.fn.initilaize - In this method, we place the animals in their appropriate positions

<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

(function($){
	$.fn.board = function(e) {
	for(let t=0;e*e>t++;)$(".container").append($("<div />"));for(let o=$(".container  div"),l=0,r=50,a=50,d=0,n=["rgb(255,225,0)","rgb(255,150,0)"],s=0;e>s++;){1&e?++d:d&1,l=0;for(let i=-9;e>i++;)$(o[e*s+i]).css({"background-color":n[d],"left":l,"top":r,"width":a,"height":a,"position":"absolute"}),l+=a,d=d+1&1;r+=a}
	};
	
	$.fn.initialize = function() {
	
	$(".container div").each(function(index) {
	$(this).css({paddingTop:"15px",textAlign:"center"});

Step 1 - Configure extra environment variables As a preface, it is best to setup some extra environment variables to make running jobs from the CLI quicker and easier. You can name these environment variables anything you want, but we will name them HADOOP_CP and HDFS_LOC to not potentially conlict with other environment variables. Open the Start Menu and type in 'environment' and press enter. A new window with System Properties should open up. Click the Environment Variables button near the bottom right.
