Spread your data on arrays as you spread nutella on your bread. pretty even.

Spread your data. for example inputting ["a","a","b"] will output ["a","b","a"].
So that if you need to bash things you do it controlled. no more nutella rests on one side!
And since it uses a odd-in-the-middle technique all the "unique" items get pushed into the middle ("aaaabc" becomes "aabcaa" f.x.).

Install via NPM (npm i spread.js) or include spread.min.js to your webpage

in NodeJS use var Spread = require('spread.js')

Spread([ARRAY<number|string>],function(err,result)):

Spread([1,2,3,3,2,3,3],function(err,res){ console.log(res) });
> ["3", "2", "3", "1", "3", "2", "3"]

Spread([ARRAY<object|array>],KEY_IN_OBJECT,function(err,result)):

Spread([{"value":1,"index":0},{"value":2,"index":1},{"value":3,"index":2},{"value":3,"index":3},{"value":2,"index":4},{"value":3,"index":5},{"value":3,"index":6}],'value',function(err,res){ console.log(res) })
> [{"value":3,"index":2},{"value":2,"index":1},{"value":3,"index":3},{"value":1,"index":0},{"value":3,"index":5},{"value":2,"index":4},{"value":3,"index":6}]

Spread.async([ARRAY<number|string>])

Spread.async([ARRAY<object|array>],KEY_IN_OBJECT)
