Extend n8n with custom JavaScript using Function Nodes

Advanced Tip: Use 'Function Nodes' in n8n to write custom JavaScript and extend your power. 💻⚖️ When pre-built nodes aren't enough, code your way to victory. Get the JS snippets for n8n at smartflowslab.com. #n8nTutorial #JavaScript #AdvancedNoCode #AutomationStrategy

Javascript challenge! let a = 10; let b = 20; [a, b] = [b, a]; console.log(a, b); Drop your answer in the comments #JavaScript #CodingChallenge #WebDevelopment #FrontendDeveloper #LearnToCode

Stop using delete to remove Array elements! 🛑 If you think the answer to the code below is 3, you're falling for a classic JavaScript trap. let numArr = [1, 2, 3, 4]; delete numArr[2]; Console.log(numArr.length) #JavaScript #WebDevelopment #CodingTips #SoftwareEngineering #FrontendDev #CleanCode

JavaScript bugs don’t just break the code… they create new dimensions of problems. 😅 Every error feels like a puzzle no one prepared you for. #JavaScript #CodingMemes #DeveloperLife #WebDevelopment

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

Today I revised an important concept in JavaScript – Arrow Functions. Arrow functions help write shorter and cleaner functions compared to traditional functions. I practiced examples like addition, subtraction, and multiplication using arrow functions. Consistent practice is helping me strengthen my JavaScript fundamentals and improve my problem-solving skills. #JavaScript #WebDevelopment #FrontendDevelopment #CodingPractice #LearningJourney

In 1978, I wrote self-modifying code on a 12-bit machine with 4KB of RAM. Technically, 4K Words; the byte wasn't its unit. But the constraint was the same. I wrote self-modifying code on it. Not because it was clever. Because it was the only option. Four lessons from that experience that I have never unlearned — and still apply to every line of software I write. → https://lnkd.in/gBB7GW9U #Javascript #winkjs #winkComposer

🚀 30 Days of JavaScript – Day 10 Today I built a small logical puzzle game called Bulls & Cows. The program generates a secret number and the player must guess it. After each guess, the program gives hints using Bulls (correct digit & position) and Cows (correct digit but wrong position). 🧠 Concepts Used: • loops • string indexing • conditional logic • problem-solving approach 🎥 Demo below 👇 Full source code in the comments. #JavaScript #CodingChallenge #ProblemSolving #WebDevelopment #LearningJavaScript

Implemented Selection Sort in JavaScript, where the smallest element is selected in each iteration and placed at its correct position. A simple yet effective way to understand sorting fundamentals and in-place operations. #JavaScript hashtag#DSA hashtag#Algorithms hashtag#Coding hashtag#WebDevelopment

Day 12 #100DaysOfCode 💻 Today I learned about Synchronous vs Asynchronous JavaScript, especially how setTimeout() and setInterval() work. JavaScript runs code synchronously by default (line by line). But functions like "setTimeout()" run asynchronously, meaning they execute later without blocking the main thread. Example: console.log("1"); setTimeout(() => { console.log("2"); }, 0); console.log("3"); Output: 1 3 2 Even with "0ms", "setTimeout" goes to the callback queue, so the synchronous code runs first. Understanding this concept helped me see how JavaScript handles non-blocking tasks. #JavaScript #AsyncJavaScript #WebDevelopment #CodingJourney #Akbiplob
