JavaScript Snippets
The snippet library collects 40 reusable JavaScript code patterns that solve everyday problems — debouncing and throttling event handlers, deep cloning objects, currying functions, formatting dates, and similar utilities that appear in almost every project. Each snippet page explains what the pattern does, when you would reach for it, and shows the complete implementation with a usage example so you can copy it straight into your codebase. Browse the collection: Debounce a Function, Throttle a Function, Deep Clone an Object, Remove Duplicates from Array, Flatten a Nested Array, Memoize a Function, Sleep / Delay Execution, Function Composition (Pipe), Get and Set URL Parameters, Shuffle an Array (Fisher-Yates), Group Array Objects by Key, Format Relative Time (time ago). Every snippet uses only standard JavaScript with no dependencies, works in modern browsers and Node.js, and links back to the relevant method references such as Array.prototype.map(), Array.prototype.filter(), Array.prototype.reduce(), Array.prototype.forEach(), Array.prototype.find(), Array.prototype.findIndex(), Array.prototype.findLast(), Array.prototype.some(), Array.prototype.every(), Array.prototype.includes(), Array.prototype.indexOf(), Array.prototype.push(), Array.prototype.pop(), Array.prototype.shift(), Array.prototype.unshift(), Array.prototype.slice(), Array.prototype.splice(), Array.prototype.concat(), Array.prototype.join(), Array.prototype.sort() so you can dig into any API it relies on.
