【実務で結構使うJavaScript Tips】 ・在庫がある商品だけを表示したい ・特定カテゴリーの記事だけを一覧に出したい ・チェックが付いた項目だけを送信したい そんな「絞り込む」っていう処理、 どう書けばいいか悩んじゃいますよね・・ そんなときはJSのfilterがかなり便利! const numbers = [1, 2, 3, 4, 5]; const evenNumbers = numbers.filter((num) => { return num % 2 === 0; }); → [2, 4] 元の配列はそのままで、 「条件に合ったものだけ」を 新しい配列として返してくれるイメージ 「こいつ絞り込みたいな」って思ったら まずは filter を思い出せばOKです👍️

Day 39 of #100DaysOfCode Today I learned about the filter() method in JavaScript, an incredibly versatile tool for working with arrays. 🔹 What it does The filter() method creates a new array with all elements that pass a test defined in a callback function. If the callback returns true, the element is kept. If it returns false, the element is excluded. If no elements pass, it returns an empty array. 🔹 Example 1 – Filter Even Numbers const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; const evenNumbers = numbers.filter(num => num % 2 === 0); console.log(evenNumbers); // [2, 4, 6, 8, 10] 🔹 Example 2 – No Matches const numbers = [2, 4, 6, 8].filter(num => num > 10); console.log(numbers); // [] 🔹 Example 3 – Filter Objects by Property const developers = [ { name: "Alice", age: 25 }, { name: "Bob", age: 30 }, { name: "Charlie", age: 35 }, { name: "David", age: 25 } ]; const youngPeople = developers.filter(person => person.age < 30); console.log(youngPeople); // [{ name: "Alice", age: 25 }, { name: "David", age: 25 }] ✨ Takeaway: The filter() method is powerful for selecting data based on conditions. Whether filtering numbers, cleaning up arrays, or narrowing down objects, it keeps code clean, efficient, and declarative. Alongside map() and reduce(), it’s a core tool every JavaScript developer should master.
🚀 Day 38 of #100DaysOfCode Today I dug deeper into callback functions and higher-order functions, two powerful concepts that shape how JavaScript handles logic and flexibility. 🔹 Callback Functions A callback is simply a function passed as an argument to another function. They allow code to be executed after another operation has finished. Example with forEach: let numbers = [1, 2, 3, 4, 5]; numbers.forEach(num => console.log(num * 2)); // Output: 2, 4, 6, 8, 10 The callback here (num => console.log(num * 2)) is run once for each element. forEach can pass element, index, and array into the callback. 🔹 Higher-Order Functions A higher-order function (HOF) either: ✅ Takes one or more functions as arguments ✅ Returns a function ✅ Or both Example: function operateOnArray(arr, operation) { let result = []; for (let i = 0; i < arr.length; i ) { result.push(operation(arr[i])); } return result; } function double(x) { return x * 2; } console.log(operateOnArray([1,2,3], double)); // [2, 4, 6] HOFs make code reusable and modular. Built-in examples: map(), filter(), reduce(). ✨ Takeaway: Callbacks give us fine control over execution, while higher-order functions unlock flexibility by letting us treat functions as data. This combination is the backbone of functional programming in JavaScript.

The correct answer is C) filter(). Explanation: The filter() method in JavaScript creates a new array containing all elements from the original array that satisfy the condition defined in the provided callback function. It does not modify the original array. For example: const numbers = [1, 2, 3, 4, 5]; const evenNumbers = numbers.filter(num => num % 2 === 0); console.log(evenNumbers); // Output: [2, 4] In this example, filter() tests each element to check if it's even and returns a new array with the even numbers [2, 4]. map() transforms each element but returns all of them. reduce() reduces the array to a single value. forEach() executes a function on each element without returning a new array. Hence, filter() is the method used to create a new array with elements that pass a test function.

JavaScript Array Methods: Your New Best Friends in Coding 🚀 Say goodbye to boring loops! JavaScript’s array methods are here to make your code cleaner, smarter, and more fun to write. Let’s break it down: 🌟 The Core Seven 1. map() – The Overachiever ✨ Transforms every element in a flash! const numbers = [1, 2, 3]; const doubled = numbers.map(num => num * 2); // [2, 4, 6] You map out the new plan, and voilà—transformation complete! 2. filter() – The Gatekeeper 🕵️ Keeps only the cool kids (or numbers, or whatever). const numbers = [1, 2, 3, 4, 5]; const evenNumbers = numbers.filter(num => num % 2 === 0); // [2, 4] If it doesn’t pass the vibe check, it doesn’t get in. 3. find() – The Treasure Hunter 🪙 Finds the first hidden gem and stops. const firstEven = numbers.find(num => num % 2 === 0); // 2 Perfect for when you’re like, “Just gimme the first one!” 4. findIndex() – The Detective 🕵️‍♀️ Finds the location of the first suspect. const firstEvenIndex = numbers.findIndex(num => num % 2 === 0); // 1 Great for pinpointing culprits in the lineup. 5. fill() – The Artist 🎨 Replaces everything with your chosen color—or value. const array = [1, 2, 3, 4]; array.fill(0); // [0, 0, 0, 0] It’s like painting your array with a single brushstroke. 6. some() – The Optimist 🤞 Checks if at least ONE element passes the test. const hasEven = numbers.some(num => num % 2 === 0); // true Just one “yes” and it’s a win! 7. every() – The Perfectionist ✅ Tests if EVERYTHING is up to standard. const allEven = numbers.every(num => num % 2 === 0); // true Perfect for the all-or-nothing crowd. --- ✨ Why These Methods Rock: Readable: Say goodbye to nested loops. Safe: Less chance of breaking things. Chainable: Build complex operations with ease. Immutable: Some methods won’t mess with your original array! --- 🔥 Pro Tips for Super Devs Use map() to transform arrays like a pro. Use filter() to keep only what you need. Use find() to snag that one golden item. Chain these bad boys to make your code unstoppable. Got a favorite array method? Share it below! 👇 Follow @sytelix for more JavaScript tips and tricks.

Code сонирхогчдод зориулсан цуврал зөвлөмж: JavaScript-ийн array-н method, filter гэдэг нь array-н элементүүдээс тодорхой шалгалт хангасан элементүүдийг шүүж, шинэ array үйлдэгч функц юм. filter нь array-н бүх элемент дээр өгөгдсөн функцийг дууддаг бөгөөд тухайн функцийн буцаах утга үнэн (true) болох элементүүдийг шинэ array-д хамруулдаг. 0 үлдэгдэлтэй тоо буюу тэгш тоо сонгох array жишээ: let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; let evenNumbers = numbers.filter(function(number) { return number % 2 === 0; }); console.log(evenNumbers); Үр Дүн: [2, 4, 6, 8, 10] Эндээс харахад, filter нь numbers array-н дотроос тэгш тоонуудыг шүүж, шинэ array, evenNumbers-г үйлдэж байна.

1 - Filter : - بينشئ array جديدة فيها العناصر اللي اجتازت الشرط اللي أنت حددته - بيتستخدم لما تحتاج تجيب مجموعة من الحاجات اللي تمشي مع شرط معين مثلا : const numbers = [1, 2, 3, 4, 5]; const evenNumbers = numbers.filter( num => num % 2 === 0 ); // evenNumbers هتكون فيها [2, 4] تابع..

Filter() Method of Array in Javscript. #bandocoin The filter() method of array in JavaScript is a useful way to create a new array with only the elements that pass a certain condition. The filter() method takes a callback function as an argument, which is executed for each element in the original array. The callback function should return a boolean value (true or false) to indicate whether the element should be included in the new array or not. The filter() method does not change the original array, but returns a new one. For example, if you have an array of numbers and you want to filter out the odd ones, you can use the filter() method like this: const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; const evenNumbers = numbers.filter(function(number) { return number % 2 === 0; // return true if the number is even }); console.log(evenNumbers); // [2, 4, 6, 8, 10] ``` The filter() method can also take a second argument, which is the value of this inside the callback function. This can be useful if you want to access some properties or methods of an object inside the callback function. #method
