The Reduce Method of a Javascript Array

• I've seen alot of confusing Youtube videos on this subject, but
• but here is an easy way of using the reduce method of a javascript array.  
• var colors=link
• ["red", "blue", "yellow", "black", "purple", "chartreuse"];

• var newcolors= colors.reduce(function(k,j){return k+ " and " +j},colors[1]);link
• "blue and red and blue and yellow and black and purple and chartreuse"
