In plain words
LDS is a JavaScript library implementing data structures using typed arrays for memory-intensive applications. It addresses the ~1.5GB memory limit of Node.js v8 by leveraging typed arrays, which operate outside this constraint. Built with CoffeeScript, the library provides basic data structure implementations for developers working with large datasets who want to remain within JavaScript rather than switching to lower-level languages.

I use CoffeeScript (Node.js) extensively to analyze large data sets. Time to time I run out of available memory provided by v8 for JS Objects and Arrays. Even in 64-bit Node.js (as of version 0.12) there is ~1.5GB memory limit. But this memory limit does not apply for Types Arrays. I don't believe this is case where we need to look for another resort like C, specially given the flexibility offered by JavaScript. LDS (Large Data Structures) is a library that implements some of basic data structure based on JavaScript Typed Arrays to overcome this memory limit issue. It's still not fine tuned to gain the best performance but very much usable. There can be considerable performance hit in when…from chethiya.github.io
