💡 Pure vs Impure Functions in JavaScript 🔹 Pure Function Same input → Same output. No side effects. const add = (a, b) => a + b; 🔸 Impure Function Depends on or changes external state. let total = 0; const addToTotal = (v) => total += v; 🚀 Why it matters? Predictable code. Easier testing. Fewer bugs. 👉 Write pure functions whenever possible. #JavaScript #CleanCode #FunctionalProgramming

Day 5/100 of JavaScript Today’s Topic: Closures in JavaScript A closure is created when a function remembers variables from its outer scope even after that outer function has finished execution Example: function outer() { let count = 0; return function inner() { count++; return count; }; } const counter = outer(); counter(); // 1 counter(); // 2 Here, the "inner" function forms a closure over the "count" variable. Even though "outer()" has finished execution, "count" is preserved. Key understanding: Closures help in maintaining state and also enable data privacy by restricting direct access to variables #Day5 #JavaScript #100DaysOfCode
