A FancyArray is an ndarray which supports slicing via indexing expressions. var ndarray2array = require( '@stdlib/ndarray-to-array' ); var FancyArray = require( '@stdlib/ndarray-fancy' ); var buffer = [ 1, 2, 3, 4, 5, 6 ]; var x = new FancyArray( 'generic', buffer, [ 6 ]...
Slicing and Spreading Combining .slice() and the spread operator allows us to replace elements nondestructively, leaving the original Array unharmed: const menu = [ "Jalapeno Poppers", "Cheeseburger", "Fish and Chips", "French Fries", "Onion Rings", ]; const newMenu = [ ...menu.slice(...
