function swapRanges$(x, i, I, j, J)
// x: an array (updated!)
// 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];
