npm install spiralloop

SpiralLoop

Ever wanted to do a for loop starting from the center instead of a corner? Now you can!

Install

js
npm install spiralloop


Usage
spiral(Lengths, [Center], Function)
$3

An array of the lengths of your loop, such as [4, 4] or [5, 3, 7]. Handles array lengths as long as you'd like.
$3

The default center is in the middle (1.5, 1.5 of a 3x3) but feel free to change this up.
$3

A function that will give paramaters of the current value. For example:


function(x, y, z) { }


If you return true in this function, it will act as a "break".
Example

js
var spiral = require('spiralloop');

spiral([3, 3], function(x, y) { console.log(x + ', ' + y); });``

npm install spiralloop
