idxToJavascript

Converts idx files into JS objects

The IDX file format is a simple format for vectors and multidimensional matrices of various numerical types.

---

I'm working on a neural network in vanilla JS, and haven't found many resources in regards of translating the IDX files into javascript.
Because of this I have made my own implementation, following the instructions as described in the MNIST database website and the MDN documentation about ArrayBuffers and TypedArrays.

Usage:

Import the convertIdx function from the idxConverter.js file.

convertIdx(fileURL).then(result => { myDataSet = result.dataSet })

Mind that the convertIdx function returns a promise (it needs to wait for the XMLHttpRequest to resolve), so you have to work around that. A better description/example of the usage can be found in the main.js file.
