Breaking up atlas-dataset into standalone functions. This module computes the median value over an array of numbers:
examples
unsorted array
The median
function sorts the array in-place before taking the middle value. In the case of an even-length array, the median is the mean of the two middle values.
const median = require("atlas-median")
console.log(median([4,3,1,2]))
// 2.5
sorted array
To avoid sorting a pre-sorted array, use a boolean flag:
...
const isSorted = true;
console.log(median([1,2,3,4,5], isSorted)) // fast
// 3
