Tests:

offsetWidth / offsetHeight (destructured and renamed)
const { offsetWidth: width, offsetHeight: height } = el; const perim = (width + height) * 2;
offsetWidth / offsetHeight (destructured)
const { offsetWidth, offsetHeight } = el; const perim = (offsetWidth + offsetHeight) * 2;
offsetWidth / offsetHeight (simple property access)
const width = el.offsetWidth; const height = el.offsetHeight; const perim = (width + height) * 2;
getBoundingClientRect() (destructured)
const { width, height } = el.getBoundingClientRect(); const perim = (width + height) * 2;
getBoundingClientRect() (simple property access)
const rect = el.getBoundingClientRect(); const width = rect.width; const height = rect.height; const perim = (width + height) * 2;
