rangeEntries (original) (raw)

Find smallest and largest entries.

Alternatives: range, rangeEntries.
Similar: minimum, maximum, range.

function rangeEntries(x, fc, fm) // x: an array // fc: compare function (a, b) // fm: map function (v, i, x)

const xarray = require('extra-array');

var x = [1, 2, -3, -4]; xarray.rangeEntries(x); // → [ [ 3, -4 ], [ 1, 2 ] ]

xarray.rangeEntries(x, (a, b) => Math.abs(a) - Math.abs(b)); // → [ [ 0, 1 ], [ 3, -4 ] ]

xarray.rangeEntries(x, null, v => Math.abs(v)); // → [ [ 0, 1 ], [ 3, -4 ] ]
