## Javascript Refractor Problem

Hi,

I would like to do the refractoring for the re-use. However, I have some problems in doing it with the following coding:

Code:
```    var prismVertexPositionBuffer;
var prismVertexPositionBuffer2;
var prismVertexPositionBuffer3;
var prismVertexNormalBuffer;
var prismVertexColorBuffer;
var prismVertexColorBuffer2;
var prismVertexIndexBuffer;
var prismVertexIndexBuffer2;
var prismVertexIndices;
var prismVertexIndices2;
var unpackedColors;
var vectices;
var normalData;
var height = 2;
var n = 12
var twoPi = 2.0 * 3.14159;

function initBuffers() {
vertices = [0, 0, 0];
vertices2 = [0, height, 0];
vertices3 = [];
normalData = [0, 0, 1];
unpackedColors = [1, 0, 0, 1];
unpackedColors2 = [];
prismVertexIndices = [];
prismVertexIndices2 = [];

for (var j = 0; j < n; j++) {
vertices = vertices.concat([Math.cos((j - 1) * twoPi / n), 0.0, Math.sin((j - 1) * twoPi / n)]);
vertices2 = vertices2.concat([Math.cos((j - 1) * twoPi / n), height, Math.sin((j - 1) * twoPi / n)]);
vertices3 = vertices3.concat([Math.cos((j - 1) * twoPi / n), 0.0, Math.sin((j - 1) * twoPi / n)]);
vertices3 = vertices3.concat([Math.cos((j - 1) * twoPi / n), height, Math.sin((j - 1) * twoPi / n)]);
normalData = normalData.concat([0, 0, 1]);
unpackedColors = unpackedColors.concat([1.0, 0.0, 0.0, 1.0]);
unpackedColors2 = unpackedColors2.concat([1.0, 0.5, 0.0, 1.0]);
unpackedColors2 = unpackedColors2.concat([1.0, 0.5, 0.0, 1.0]);
prismVertexIndices = prismVertexIndices.concat([0, j + 1, (j + 1 < n ? j + 2 : 1)]);
prismVertexIndices2 = prismVertexIndices2.concat([j * 2, j * 2 + 1, (j + 1 < n ? j * 2 + 2 : 1)]);
prismVertexIndices2 = prismVertexIndices2.concat([j * 2 + 1, (j + 1 < n ? j * 2 + 2 : 1), (j + 1 < n ? j * 2 + 3 : 2)]);
}
}```
I want to extract the content of initBuffer() into another js file as a function. However, when I do it, the parameters cannot be returned. Is there any methods to refractoring this code?
