Script Preparation code:
window.fdeq = function equal(a, b) { if (a.length !== b.length) return false; for (let i = 0; i < a.length; i++) { if (a[i] !== b[i]) return false; } return true; }; window.foo = Array.from({length: 40}, () => ([Math.random() * 40, Math.random() * 40])); window.foo2 = JSON.parse(JSON.stringify(window.foo.slice())); window.fox = JSON.parse(JSON.stringify(window.foo.slice(0, 30))).concat(Array.from({length: 10}, () => ([Math.random() * 40, Math.random() * 40]))); window.bar = Array.from({length: 40}, () => ([Math.random() * 40, Math.random() * 40]));
Tests:
loop same
fdeq(window.foo, window.foo2);
loop similar
fdeq(window.foo, window.fox);
loop different
fdeq(window.foo, window.bar);
stringify same
JSON.stringify(window.foo) === JSON.stringify(window.foo2)
stringify similar
JSON.stringify(window.foo) === JSON.stringify(window.fox)
stringify different
JSON.stringify(window.foo) === JSON.stringify(window.bar)
