Buat function buildTransition(property, duration, easing) yang mengembalikan string CSS transition shorthand.

Contoh: buildTransition("opacity", "0.3s", "ease-out") → "opacity 0.3s ease-out"

Lalu buat function buildMultiTransition(transitions) yang menerima array of objects [{ property, duration, easing }] dan mengembalikan string transition gabungan yang dipisahkan koma.

Contoh: buildMultiTransition([{ property: "opacity", duration: "0.3s", easing: "ease" }, { property: "transform", duration: "0.5s", easing: "ease-out" }]) → "opacity 0.3s ease, transform 0.5s ease-out"

Hint

• Format CSS transition: "property duration easing". Contoh: "opacity 0.3s ease-out".
• buildTransition(property, duration, easing): return `${property} ${duration}s ${easing}`. buildMultiTransition(array): join dengan ", ".
• buildMultiTransition([{property:"opacity", duration:0.3, easing:"ease"}, ...]) → "opacity 0.3s ease, transform 0.5s ease-out".
