Script Preparation code:
var vertices = [ [1, 0, 0, 0], [0, 1, 0, 0], [0, 0, 1, 0], [0, 0, 0, 1], ] var myCopy = null;
Tests:
JSON.stringify
myCopy = JSON.parse(JSON.stringify(vertices));
slice
myCopy = vertices.slice();
Array from
myCopy = Array.from(vertices)
Spread
myCopy = [...vertices]
structuredClone
myCopy = structuredClone(vertices)
