How does Garbage Collection work?

TLDR Garbage collection is a crucial automatic memory management feature used in many programming languages. Java offers multiple garbage collectors tailored to different scenarios, Python employs reference counting alongside a cyclic collector to handle circular references, and GoLang utilizes a concurrent mark-and-sweep garbage collector to minimize application pauses. Additional topics include tools for designing fault-tolerant systems and key system design trade-offs.

Bye Bye, Try-Catch Blocks: Meet JavaScript's Safe Assignment Operator Proposal😉

The proposed Safe Assignment Operator (`?=`) in JavaScript aims to simplify error handling by reducing the need for traditional try-catch blocks. This operator transforms function results into a tuple, improving code readability and consistency across APIs. It also automatically handles errors, enhancing security. Inspired by constructs in languages like Go, Rust, and Swift, it supports integration with Promises and async functions and offers customizable error handling via `Symbol.result`.

What’s the Difference Between interface and @interface in Java?'

TLDR An interface in Java specifies a behavior that implementing classes must fulfill, containing method signatures without implementations, and supporting abstraction, multiple inheritance, and loose coupling. On the other hand, the @interface is used to define custom annotations that add metadata to code elements for use during compilation or runtime by tools and frameworks. Key annotations like @Retention and @Target further specify how and where these annotations can be applied.

Good Commit ✅ VS. Bad Commit ❌: Best Practices for Git

Good commits are crucial for maintaining a clean and understandable project history in Git. Characteristics of good commits include being atomic and focused, having descriptive messages, following conventional guidelines, being tested and verified, and being properly scoped. Conversely, bad commits are large and unfocused, have vague or misleading messages, combine unrelated changes, and contain incomplete or untested code. Best practices for good commits involve committing often but meaningfully, writing clear messages, using branches effectively, reviewing and squashing commits, and automating testing.
