🤔 How do you decide between using a 𝗦𝗲𝘁 or an 𝗮𝗿𝗿𝗮𝘆 in #JavaScript? Recently I realized that I often reach for arrays by default, even in cases where a Set would be a better fit: when I only care about unique values and fast lookups, not about order. But in many everyday cases with small collections, arrays are still perfectly fine and often more readable. I’m currently trying to be more intentional: if I think “collection of unique things”, I reach for Set; if I need order, duplicates or array utilities, I stick with arrays. How do you handle this in your projects? #JavaScript #TypeScript #CleanCodeSolutions #WebDevelopment #Frontend
You ask Chat GPT , If it suggests to use Set, You should use Array 👍🏻
They choose themselves. Do the elements need to be unique? Use a Set. If you're manually checking that an array doesn't contain a value because ALL values must be unique, you picked the wrong data structure.
