Day 1 of Building a new application! #javascriptdeveloper #jsdeveloper

Day-1 | Week-1 JavaScript Foundations Completed! 🚀 Today I stepped into the core of JavaScript in Harkirat’s Cohort 2.0. Key takeaways from today’s class: 🔹 Why languages exist & what JS solves 🔹 Interpreted vs Compiled languages 🔹 Strict vs Dynamic typing 🔹 Single-threaded nature of JS 🔹 Primitives vs Complex data types 🔹 Functions callbacks in JS 🔹 Understanding how runtime executes code I even wrote my first function callback flow to return data! This foundation is going to power everything ahead – Node.js, async, APIs & backend logic. #JavaScript #NodeJS #WebDevelopment #FullStack #CodingJourney #100DaysOfCode #LearningInPublic #HarkiratCohort #JSDeveloper #TechJourney

👨‍💻 بعد فترة شغل وتجربة في مجال الـ Frontend باستخدام React، حبيت أشارك شوية نصايح لأي حد داخل المجال أو حابب يطور من نفسه: ⸻ 1 - افهم الأساسيات الأول قبل ما تغوص في React، اتأكد إنك متمكن من JavaScript (خصوصًا ES6 )، زي map, filter, destructuring, و async/await. كمان مهم تفهم الـ DOM كويس وإزاي تتعامل مع الـ events. ⸻ 2 - اشتغل بـ Functional Components و Hooks بلاش تشتغل بـ class components في أي مشروع جديد. ركز على useState, useEffect, useMemo, useCallback, و useRef. دول فعلاً بيفرقوا في الأداء والتنظيم. ⸻ 3 - نظم ملفات المشروع نظم شغلك من البداية، سواء feature-based أو component-based structure. ده بيسهل عليك الصيانة والتطوير بعد كده. ⸻ 4 - افهم State Management في البداية، useState و useContext كفاية. بس مع كبر المشروع، هتحتاج حاجة زي Zustand أو Redux Toolkit. شخصيًا بحب أبسط حل ينجز ويكون سهل في القراءة. ⸻ 5 - اتقن CSS جربت كذا طريقة، واللي ارتحت له Tailwind CSS – سريع ومرن جدًا. لكن لو هتشتغل مع فريق، اتفقوا على Style واحد سواء SCSS أو CSS Modules. ⸻ 6 - متنساش Testing مهما كنت شايف إن المشروع بسيط، وجود اختبارات (حتى لو بسيطة بـ React Testing Library) بيريّحك جدًا على المدى الطويل وبيخلي الكود أكثر ثقة. ⸻ 7 - حسّن الأداء راقب الأداء باستخدام React.memo, useMemo, useCallback. استخدمتهم في كذا مشروع وفعلاً فرقوا في سرعة الريندر، خاصة لما بتتعامل مع Lists كبيرة. ⸻ 8- Debugging Tools React Dev Tools من أهم الأدوات اللي لازم تتعلم تستخدمها كويس. ودايمًا راقب الـ Network و Console وانت شغال. ⸻ 9 - اتفرج على كود غيرك GitHub كنز، اتعلمت كتير من مشاريع ناس تانية. شوف إزاي بيبنوا الكومبوننتس، بيفصلوا الـ logic، وبيتعاملوا مع الأخطاء. ⸻ 10 - ابني مشاريع حقيقية مهما قريت أو اتفرجت على فيديوهات، مفيش زي التطبيق العملي. كل مشروع هتعمله هتطلع منه بحاجة جديدة. أنا بدأت بـ Todo App وبعدها Blog Dashboard، وكل واحد فيهم علمني حاجة. #ReactJS #FrontendDevelopment #WebDev #JavaScript #CodingTips #LearnReact #100DaysOfCode #DevCommunity #TechTips #ReactDeveloper #CodeNewbie #WomenWhoCode #CleanCode #TailwindCSS #Zustand #ReduxToolkit #TestingInReact #JSDeveloper #BuildInPublic #ريأكت #تعلم_البرمجة #نصائح_برمجية #واجهات_أمامية #تطوير_الويب #جافاسكربت #برمجة #نصائح_ريأكت

🔥 How to Flat an Array in JavaScript In JavaScript, you can flatten nested arrays using multiple methods. A thread 🧵👇🏻 #javascript #learnjavascript #javascriptdeveloper #javascriptprojects #javascripttricks #reactjs #nextjs #nodejs #javascriptcourse #javascriptforbeginners #javascriptcoding #jsdeveloper #javascriptcode

The full form of HTML is HyperText Markup Language. 🔥 What is an HTML Tag? HTML tags are special keywords used to create the structure of a web page. 👉 Syntax: <tagname>Content goes here...</tagname> ✅ Example: <h1>Hello World</h1> Here: <h1> = Opening Tag Hello World = Content </h1> = Closing Tag 🔑 Types of HTML Tags: - Type Paired Tags Example <p></p> Have opening & closing tags ______________________________ - Type Self-Closing Tags Example <img /> No closing tag ______________________________ - Type Empty Tags Example <br /> Only opening tag (used for line breaks) Most Common HTML Tags 🔥 <h1>-Heading <p>-Paragraph <a>-Link <img>-Image <div>-Container <span>-Inline container <ul>-Unordered List <table>-Table 🎯 Bonus Tip: HTML is not case-sensitive ➡️ <TITLE> = <title> #webdevelopment #nextjs13 #reacthooks #codinglife #developercommunity #jsdeveloper #javascript #reactjs #nextjs #frontenddeveloper #fullstackdeveloper #codingtips #programmingtutorial #learnjavascript #ai #chatgpt #100DaysOfCode #webdev

JavaScript array methods 🚀🔥 1. Adding & Removing Elements push(item) → Adds an item at the end of the array. pop() → Removes the last item from the array. unshift(item) → Adds an item at the beginning of the array. shift() → Removes the first item from the array. ----------------------------------------------------- 2. Searching in an Array indexOf(item) → Returns the index of the first occurrence of an item (or -1 if not found). lastIndexOf(item) → Returns the index of the last occurrence of an item. includes(item) → Returns true if the item exists in the array, otherwise false. find(callback) → Returns the first matching element based on a condition. findIndex(callback) → Returns the index of the first matching element based on a condition. ----------------------------------------------------- 3. Modifying or Transforming Arrays map(callback) → Creates a new array by modifying each item. filter(callback) → Creates a new array with only the items that match a condition. reduce(callback, initialValue) → Reduces the array to a single value (e.g., sum of all numbers). forEach(callback) → Runs a function for each item (but doesn’t create a new array). some(callback) → Returns true if at least one item matches a condition. every(callback) → Returns true if all items match a condition. ----------------------------------------------------- 4. Sorting & Reversing sort(compareFunction) → Sorts the array (default is ascending, but can be customized). reverse() → Reverses the order of the elements in the array. ----------------------------------------------------- 5. Extracting & Combining Arrays slice(start, end) → Extracts a portion of an array (without modifying the original). splice(start, deleteCount, item1, item2, …) → Changes the array by adding/removing elements. concat(array2, array3, …) → Joins two or more arrays into a new array. flat(depth) → Flattens nested arrays into a single array (default depth is 1). join(separator) → Converts an array to a string, with elements separated by a given character. ----------------------------------------------------- 6. Converting & Checking Arrays toString() → Converts an array to a string. Array.isArray(value) → Checks if a value is an array (true or false). #JavaScript #JSDeveloper #LearnJavaScript #JavaScriptTutorial #Coding #JavaScriptArrays #ArrayMethods #JSArrayTips #CodingWithJS #JavaScriptTricks #WebDevelopment #coder #CodeNewbie #FrontendDeveloper #coding #ProgrammingTips #100DaysOfCode #react
