intersperse

Place a separator between every value.

Similar: interleave, intermix, interpolate, intersperse.

function intersperse(x, v)
// x: an array
// v: separator

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

var x = [1, 2, 3];
xarray.intersperse(x, 10);
// → [ 1, 10, 2, 10, 3 ]

var x = [1, 2, 3, 4];
xarray.intersperse(x, 10);
// → [ 1, 10, 2, 10, 3, 10, 4 ]
