vec2

• using function Array() { [native code] }

  • rotate

    • rotation around world origin [0, 0]

      • should return the rotated vector0ms ‣

        const expected = [0, -1];
        testV2WithAndWithoutDestApprox((a, b, angle, newDst) => {
          return vec2.rotate(a, b, angle, newDst);
        }, expected, [0, 1], [0, 0], Math.PI);
