JavaScript Deep Clone Object
Creates a true deep copy of any serialisable object or array — nested objects, arrays, dates (as ISO strings). Uses structuredClone when available (modern browsers/Node 17+) and falls back to JSON round-trip for older environments. Does not handle functions, undefined, or circular references.

JavaScript Deep Merge Objects
Recursively merges two or more objects, combining nested properties rather than overwriting them. Unlike Object.assign or spread, this preserves deep keys from all sources. Useful for merging configuration objects, default settings with user overrides, and API response patching.

JavaScript Pick & Omit Object Keys
pick returns a new object containing only the specified keys. omit returns a new object with the specified keys removed. Both are pure (non-mutating) and handle missing keys gracefully. Essential for cleaning API payloads, projecting data shapes, and avoiding over-sending sensitive fields.

JavaScript Flatten Object (Dot Notation)
Flattens a deeply nested object into a single-level object with dot-notation keys. Useful for comparing configs, building form field names from nested data, logging structured objects to analytics, or preparing data for flat key-value stores like Redis or environment variables.

JavaScript Deep Equal Comparison
Performs a recursive structural equality check between two values. Handles primitives, arrays, objects, Dates, Maps, Sets, null, and undefined. Faster than JSON.stringify comparison (which ignores undefined and Map/Set), and avoids the false-positive trap of == or Object.is for nested structures.
