swapRanges (original) (raw)

Exchange two ranges of values.

Alternatives: swapRanges, swapRanges$.
Similar: swap, swapRanges.

function swapRanges(x, i, I, j, J) // x: an array // i: begin index of first range // I: end index of first range (exclusive) // j: begin index of second range // J: end index of second range (exclusive)

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

// Example for swapRanges var x = [1, 2, 3, 4, 5]; xarray.swapRanges(x, 1, 3, 3, 5); // → [ 1, 4, 5, 2, 3 ]
