Rest and spread operator in javascript

Absolutely 👍 — here are several practical and clear examples of the rest operator ( ... ) in JavaScript, covering functions, arrays, and objects 👇 🧮 1. Rest in Function Parameters When you don’t know how many arguments a function will receive: function multiply ( factor, ...numbers ) { return numbers. map ( n => n * factor); } console . log ( multiply ( 2 , 1 , 2 , 3 , 4 )); // Output: [2, 4, 6, 8] 👉 factor gets the first argument ( 2 ), and ...numbers collects the rest into an array [1, 2, 3, 4] . 🧑‍🤝‍🧑 2. Rest with Array Destructuring You can collect remaining array elements into a variable: const fruits = [ "apple" , "banana" , "mango" , "orange" ]; const [first, second, ...others] = fruits; console . log (first); // "apple" console . log (second); // "banana" console . log (others); // ["mango", "orange"] 👉 The rest operator gathers all remaining elements afte...

Role of box-sizing and its attributes in css

🧱 Default behavior (content-box) By default, browsers use: box-sizing : content-box; This means: Total element width = content width + padding + border So if you have: .container { width : 300px ; padding : 20px ; border : 5px solid black; } Then the total visible width becomes: 300 (content) + 40 ( left + right padding) + 10 ( left + right border) = 350 px ⚠️ The box becomes wider than 300px , which can cause overflow or layout shifts. ✅ With box-sizing: border-box When you use: box-sizing : border-box; the formula changes to: Total element width = width (including padding + border) So the same CSS now behaves like this: width = 300 px (total) → content area = 300 - ( 40 padding + 10 border) = 250 px ✅ The box stays exactly 300px wide — no overflow. 🎯 Why it’s useful Prevents unexpected overflow due to padding/borders Makes responsive layouts easier Keeps your box sizes consistent You can trust width to be the actu...
