querySelector vs querySelectorAll: Key Differences in CSS Selection

⚡ Day 3 – querySelector vs querySelectorAll (Real Difference) Both methods use CSS selectors. But they return different results — and that difference matters. 🔹 querySelector() ✔ Uses CSS selectors ✔ Returns the first matching element ✔ Returns a single element ✔ Stops after first match 🔹 querySelectorAll() ✔ Uses CSS selectors ✔ Returns all matching elements ✔ Returns a NodeList ✔ Can loop using forEach() 🧠 Key Difference: querySelector() → first match only querySelectorAll() → all matching elements ⚠️ Important: A NodeList is not an Array, but it supports forEach(). Understanding small DOM differences like this helps avoid common bugs and builds a strong JavaScript foundation. #JavaScript #WebDevelopment #Frontend #DOM #JSConcepts #Coding #100DaysOfCode
