itk.js ====== [](https://dev.azure.com/InsightSoftwareConsortium/ITKModules/_build/latest?definitionId=11&branchName=master) [](https://circleci.com/gh/InsightSoftwareConsortium/itk-js) [](https://zenodo.org/badge/latestdoi/45812381) *itk.js* combines [Emscripten](http://emscripten.org/) and [ITK](https://www.itk.org/) to enable high-performance spatial analysis in a JavaScript runtime environment. The project provides tools to a) build C/C++ code to JavaScript ([asm.js](http://asmjs.org/)) and [WebAssembly](http://webassembly.org/), b) bridge local filesystems, native JavaScript data structures, and traditional file formats, c) transfer data efficiently in and out of the Emscripten runtime, and d) asynchronously execute processing pipelines in a background thread. *itk.js* can be used to execute [ITK](https://www.itk.org/), [VTK](https://www.vtk.org/) or arbitrary C++ codes in the browser or on a workstation / server with Node.js. For more information, please see [the project documentation](https://insightsoftwareconsortium.github.io/itk-js/).
