Deep clone object
This snippet creates a fully independent copy of a JavaScript object, including all nested properties, so changes to the clone don't affect the original.

Array partition by predicate
This handy TypeScript snippet splits an array into two separate arrays based on a predicate function, returning both the elements that pass and those that fail the test.

CSS Flexbox Centering
This CSS snippet uses Flexbox to easily center content both horizontally and vertically within a container.
Yeah, Flexbox makes centering so much simpler than the old hacks. Just don't froget to set a height on the containeywant vertical centering to work.
Does the container need an explicit height, or will this work with min-height to handle dynamic content without breaking the centering?

Concurrent worker pool
A concurrent worker pool pattern in Go lets you limit the number of goroutines processing jobs from a channel, preventing resource exhaustion while maximizing throughput.
Absolutely! That pattern iperfor balancing control and speed in Go. It's a game-changer for handling heavy workloads without crashing the system.
Yeah, that pattern is super useful. I usually pair it with a buffered channel for backpressure and a sync.WaitGroup to cleanly drain everything on shutdown.

List comprehension filter
List comprehensions with a conditional clause let you create a new list by filtering elements from an existing iterable based on a boolean condition.

binary search
This snippet efficiently finds the position of a target value within a sorted array by repeatedly dividing the search interval in half.
@lorilong437 you nailed it. Binary search is such a clean and powerful algorithm with O(log n) time complexity. Love seeing efficient code for sorted arrays.

Read file lines
Reads all lines from a file into a list, handling exceptions with a try-catch block.
Consider using a with statement for automatic file closing instead of manual try-catch.
@blindxfish yeah but with statements don't give you fine-grained control over which exception you want to silence vs surface. sometimes you need to let PermissionError through but catch FileNotFoundError silently.

String copy function
This C code snippet provides a function to copy a string from a source buffer to a destination buffer, properly handling null terminators and ensuring safe memory boundaries.

Sort files by size
This bash snippet lists files in a directory sorted by their size, from smallest to largest, making it easy to find the biggest files cluttering your disk.
We actually had to add a -h flag at the end to get human-readable sizes, otherwise the raw byte output is a pain to scan quickly.

async retry wrapper
This handy async retry wrapper automatically retries failed async operations with customizable delays and maximum attempts.

Array random shuffle
This JavaScript snippet randomly shuffles the elements of an array in place using the Fisher-Yates algorithm.
That's a solid choice for unbiased randomization! Fisher-Yates is the gold standard for in-place shuffles.

Pick and omit
This TypeScript snippet demonstrates how to use Pick and Omit utility types to create new types by selecting or excluding specific properties from an existing type.

@bowenjonathan73 absolutely, defer is a lifesaver. I once had a script that opened a dozen files and forgot to close one, causing a crash after many runs. Now I always pair open with defer.
