Day 13 of #LearnJSWithMe Event Loop (Understanding async) - JS is single-threaded, but async feels magical because of the Event Loop. Order of execution: 1) Call stack 2) Microtasks (Promises) 3) Macrotasks (setTimeout) Master this = master async #JSbytes #JStips #TechTips

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 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 5 of #LearnJSWithMe De-structuring = easier access to object/array values. const user = { name: 'John', age: 10 }; const { name, age } = user; console.log(name, age); // John 10 Simple & readable !! #Javascript #JSTips #JSbytes #LearnJavascript #TechTwitter #TechPeople

Day 3 of #LearnJSWithMe Arrow functions are shorter & lexically bind this. Old - const add = function(a, b) { return a + b; } New - const add = (a, b) => a + b; Less code, fewer bugs! ⚡ #JSTips #TechTips #LearnJS #Javascript #ReactJS #TechInterview #JSbytes

What’s the one JavaScript concept that finally clicked for you? Mine was understanding how map() and filter() actually work 🤯 Drop yours 👇 Let’s learn from each other. #CodeNewbie #JavaScript #JSTips #Programming #CodeCommunity

JavaScript Tip - Want to check if an array is empty? Instead of doing - if (arr.length === 0) { ... } just write - if (!arr.length) { ... } That's it !! Cleaner and shorter. #JsTips #Javascript #TechJobs #TechTweets #REACT #NextJs

In JavaScript, mastering Promises and async/await can tame callback hell. Wrap asynchronous operations in Promises, then use await in an async function to handle them sequentially without nesting. #SeaStreamTech #JSTips #AsyncJS

Did you know? 🧠 Use `Array.from()` instead of the spread operator to create a shallow copy of an array-like object. It handles more complex scenarios! This can save you time when working with JavaScript frameworks. #jsTips

JS Tip No. 39 The search() method searches a string for a specified value and returns the position of the match.👀 The search value can be a string or a regex.💁🏻 It is -1 if no match is found #100DaysOfCode #javascript #JSTips #Nodejs #reactjs #React #javascriptdeveloper

JS Tip No. 44 A very useful one👀 ES6 supports computed object property names, which allows you to put an expression in brackets [], that will be computed as the property name/key👀 #100DaysOfCode #javascript #JSTips #typescript #JSDaily #Nodejs #javascript30 #reactjs #React

JS Tip No. 42 Called “IIFE” ( IIFE - immediately invoked function expression) is an anonymous function expression that is immediately invoked #100DaysOfCode #javascript #JSTips #Nodejs #reactjs #React #javascriptdeveloper

JS Tip No. 45 Rest syntax looks like spread syntax but is used for destructuring arrays and objects. Rest syntax collects multiple elements and condenses them into a single element #100DaysOfCode #javascript #JSTips #typescript #JSDaily #Nodejs #javascript30 #reactjs #React

JS Tip No. 36 If you want to convert a float to an integer, you can use Math.floor(), etc.👀 But there is also a faster way using |, the bitwise OR operator.💁🏻 #100DaysOfCode #javascript #JSTips #TypeScript #JSDaily #Nodejs #javascript30 #reactjs #React

JS Tip No. 41 New in JS with ES6/ES2015, if you want to define an object whose keys have the same name as the variables, you can use the shorthand and simply pass the key name 👀💁🏻 #100DaysOfCode #javascript #JSTips #Nodejs #reactjs #React #javascriptdeveloper
