A JavaScript library providing modular multidimensional array views over 1D typed arrays, similar to numpy arrays. It supports constant-time slicing, transposing, and flipping without copying underlying data, and works in both Node.js and browsers.

Use cases

• work with multidimensional arrays in javascript
• numpy-like arrays for node.js
• slice and transpose matrices without copying data
• represent images or audio as typed arrays
• implement grid-based simulations like game of life
• matrix operations in the browser

When to choose

• you need efficient n-dimensional array views over typed arrays in JavaScript
• you want zero-copy slicing, transposing, or subarray operations
• you're porting MATLAB or numpy numerical code to JavaScript

When to avoid

• you need built-in linear algebra or FFT operations - use ndarray companion modules or math.js
• you want a batteries-included numerical computing environment rather than a low-level array primitive
• your project uses modern bundlers without CommonJS compatibility
