fromArray - nodef/extra-array-view GitHub Wiki
Convert array range to array view.
function fromArray(x, i, I)
// x: an array
// i: begin index [0]
// I: end index [|x|]
const xarrayView = require('extra-array-view');
// Example for fromArray
var x = [10, 40, 30, 20, 50];
var y = xarrayView.fromArray(x, 1, 4);
y[0] = 41;
y[1] = 31;
y[2] = 21;
x;
// → [ 10, 41, 31, 21, 50 ]
y.push(60);
// → 5 (NOP, array view is not resizable)
x;
// → [ 10, 41, 31, 21, 50 ]
y.slice(0, 2);
// → [ 41, 31 ]
