als-statistics/lib/table/compute.js

A powerful and lightweight JavaScript library for descriptive statistics, regression, clustering, outlier detection, and noise analysis using a flexible table/column architecture.

function compute(fn, { n, columns }) {
   const values = [];
   let j = 0;
   for (let i = 0; i < n; i++) {
      const obj = {}
      for (let colName in columns) {
         obj[colName] = columns[colName]._values[i]
      }
      values.push(fn(obj, j))
      j++
   }
   return values
}
