Tests:

Create In Loop
for (let = 0; i < 1000; i++) { const obj2 = { a : 0.0, b: 0.0, x : 0.0, y :0.0, z :0.0 } for (let g = 0; g < 10; g++) { obj2.a += 10; obj2.b += 20; obj2.x += 30 obj2.y += 40 obj2.z += 50 } }
Reset in Loop
for (let = 0; i < 1000; i++) { obj.a = 0.0; obj.b = 0.0; obj.x = 0.0; obj.y = 0.0; obj.z = 0.0; for (let g = 0; g < 10; g++) { obj.a += 10; obj.b += 20; obj.x += 30 obj.y += 40 obj.z += 50 } }
