Better Math in JavaScript?

As a software engineer working on data visualization and scientific computing projects, I've often found JavaScript's native math capabilities lacking. The hunt for robust standard library led me to stdlib-js.

The promise of stdlib-js

The stdlib project caught my eye with its impressive set of features:

Comprehensive mathematical functions
Focus on numerical precision
Cross-platform consistency
Extended functionality beyond native Math

Benchmarking Reality

I ran benchmarks comparing stdlib-js against native JavaScript Math operations across 100,000 rows of data. The results were surprising:

The Good

Basic operations showed modest improvements:

sqrt: 6.23% faster
round: 3.02% faster
floor: 2.02% faster

The Not So Good

Complex operations took a significant hit:

exp: 189.85% slower
log10: 59.37% slower
trig functions: 25-33% slower

Precision Trade-off

The precision differences were minimal, with a maximum difference of 4.441e-16. Most operations whoed identical results between stdlib-js and native Math.

When to Use stdlib-js

Basic mathematical operations
Projects requiring guaranteed cross-platform behavior
Cases where consistent results matter more than raw speed

Looking Forward

There's potential for improvement - converting stdlib-js to WebAssembly could boost performance by running close to native speed, particularly for those complex operations currently showing significant slowdown. But until that happens, the choice between stdlin-js and native Math requires careful consideration of your specific needs.

Bottom Line

stdlib-js is a solid library taht delviers on its promise of consistency and extended functionality. However, the performance trade-offs mean it's not always the best choice. For my projects, I'll be using native approach and maybe in the future will try to compile stdlib-js to WASM to test if its really faster.

Have you tried stdlib-js in your projects? I'd be curious to hear about your experiences with mathematical computations in JavaScript.
