На повестке дня "Связанный список" (Linked list) 😑.
Базовая структура данных, состоит из так называемых узлов, где хранятся данные и ссылок на последующие узлы.

Преимущества ✔️
- Разный порядок элементов в памяти, в то время как порядок списка задается явно;
- Динамичность размера. В некоторых языках программирования при создании массива, нужно задавать его размер.

Недостатки ❌
- Время доступа к элементу ленейное;
- Дополнительный расход памяти. На каждое значение прикрепляется указатель на след. узел.

This post is about Cumulative Layout Shift(CLS) in browsers.
1. Whats this?
2. Why affects to performace?
3. How can be improved?


1. Cumulative Layout Shift (CLS) is a performance metric that quantifies how much content on a webpage shifts unexpectedly during the loading process. These shifts can affect not only the user experience but also the site's SEO and performance 😐

2. A high CLS score indicates a poor user experience, as frequent content shifts may lead users to click on unintended elements. This instability can increase bounce rates and negatively impact search engine rankings, making it crucial to optimize.

3. Optimization has varios strats, but coomon are:
- Reserve Space: Specify the width and height, reserve space for images and other interactive elements. If its not specified browser calculates its size after this content loaded and this leads to shifting the entire page 😧

- Avoid Dynamic Content Above Static Content: DO NOT INSERT DYNAMIC CONTENT ABOVE EXISTING!!! 🔫 Common mistake, you can meet it on different pages, where ads pushed into some block and this block shifts all stuff below 🔫

- Font Loading Strategies: Use CSS's `font-display: swap` to ensure text remains visible during font loading, or preload fonts to avoid FOIT (Flash of Invisible Text) 👍

Any programming language is just a tool. And saying "java sucks, c# is better" is a teenage level thinking. 👎
Each language is a tool, which reveals itself depending on the skill of its over.

java sucks tho

#lifehack #js

If you are using JavaScript, you know that importing code from different directories can be a pain in the butt 🥺

Example:

// some js file
import add from '../../utils/add.js'
import java from '../../lowiq/java.js'
import { brain } from '../../../lib/brain.js'

You can end this madness with relative paths with a simple solution (if you use VSCode).
1. Add `jsconfig.json` in the root of the project
2. Add "paths" config and define your needed paths with any keyword

{
...
  "paths": {
    "@utils": ["./utils/*"],
    "@sht": ["./lowiq/java.js"],
    "@lib": ["./lib/*"]
  }
...
}

3. Change relative paths to keyworded paths. Update the code from the example above to:

// some js file
import add from '@utils/add.js'
import java from '@sht'
import { brain } from '@lib/brain.js'

In the post, I wrote about linked lists. Now let's review the upgraded version of it.


Meet the Doubly Linked List 😎

A doubly linked list consists of a sequence of elements, each containing two pointers. One pointer links to the previous node, and the other points to the next node. It supports the following operations: insertion, deletion, and traversal.

Pros ✔️
- Badass name 🖕
- Traversing in both directions 🃏
- More efficient operations (delete, insert) 👍
- Dynamic size 💪

Cons ❌
- Extra pointers lead to more memory consumption 🥰
- Time complexity is still O(n) 🐌
- Implementation is harder, with more edge cases to consider 😓

Use Cases
Doubly linked lists can be used when you need bidirectional traversal, such as in browser history, music playlists, blockchain, undo/redo functionality in text editors, etc.
