A performance comparison between js and wasm when running an O(n) algorithm in the browser.

JS vs WASM performance analysis

This analysis attempts to compare the performance of JavaScript against WebAssembly when running a large number of iterations of an O(n) algorithm.

The algorithm consists of a method of minimising a simple objective function (paraboloid) using the Monte Carlo technique. The method was implemented in JavaScript and C++, and the generated WebAssembly code was compiled with Emscripten.
