Day 12 of #LearnJSWithMe Closures = a function remembers its parent scope, even after the parent is gone. function outer() { let count = 0; return () => count++; } This is how private variables & memoization work in JS. #JSbytes #LearnJS #letsconnect #TechTips #TechPeople
Day 11 of #LearnJSWithMe Hoisting = JS moves declarations to the top. But remember: only declarations, not initializations. console.log(x); // undefined var x = 5; With let & const, you get a Temporal Dead Zone instead of silent bugs. #JSbytes #JSTips #LearnJS #TechNews

Day 9 of #LearnJSWithMe Stop breaking your app with undefined errors! console.log(user?.profile?.email) If any property doesn’t exist, JS returns undefined - not a crash 💥 One of the most underrated ES features! #JSbytes #LearnJS #Javascript #JSTips #LearnJavascript
Day 10 of #LearnJSWithMe Running async calls one-by-one? That’s slow 🫤 Use Promise.all() to run them in parallel : await Promise.all([fetchUser(), fetchPosts(), fetchComments()]); Faster results, cleaner async handling. #JStips #JSbytes #LearnJS #letsconnect
Day 7 of #LearnJSWithMe map() transforms every element in an array - no loops needed. const prices = [100, 200, 300]; const gst = prices.map(p => p * 1.18); console.log(gst); // [118, 236, 354] When you map, you think functional. #JSTips #JSbytes #LearnJS #TechTips
Day 6 of #LearnJSWithMe The spread operator (...) makes copying & merging arrays/objects effortless. const nums = [1, 2, 3]; const copy = [...nums, 4, 5]; console.log(copy); // [1, 2, 3, 4, 5] Cleaner than concat() - and super handy for immutability! #LearnJS #JSbytes #JStips
