React 19 Beta Release introduces new concepts like Actions to simplify state management and error handling in React applications.
React 19 enhances form handling with features like useActionState and useOptimistic hooks, improving data submission processes and error management.
New features in React 19 like useDeferredValue, Advanced Document Metadata Management, and Resource Loading APIs enhance performance and provide better control over rendering.
Data stored on the stack is static, fixed in size, with a fixed lifecycle, and cannot be referenced across different stack frames.
Data stored on the heap is dynamic, not fixed in size, has a flexible lifecycle, and can be referenced across different stack frames.
Various programming languages use different memory management approaches, like manual management in C, garbage collection in Java, ARC in Objective-C and Swift, and ownership mechanism in Rust.
Node.js has started to support ECMAScript Modules (ESM) natively with version 22, making it easier to use modern JavaScript modules alongside CommonJS (CJS) modules.
ESM allows for synchronous and asynchronous loading, but Node.js' support for it is currently experimental and comes with limitations like not supporting top-level 'await'.
The addition of synchronous loading for ESM in Node.js simplifies interoperability between ESM and CJS, easing the transition to ESM and potentially reducing module size in projects.
Reading a large file at once in Node.js can be memory intensive, particularly for files above 1.4GB.
Utilizing the Readline API in Node.js to read files line by line can significantly reduce memory usage compared to reading the entire file at once.
Consider using npm modules like n-readlines for more advanced file reading needs, as they can efficiently read files line by line without loading the entire content into memory.
Use a text editor when committing to Git to add multi-line messages for a more detailed description. You can skip the -m flag and use your preferred text editor for multiple lines.
Consider using multiple -m options in Git commits to create separate paragraphs for a commit title and description. This helps organize your commit message and can be viewed more clearly in git log.
Another way to add multi-line messages in Git is to open quotes, press Enter for each line of the message, and then close quotes. This is a simple method to structure your Git commit messages.
