dequal is a tiny (304B to 489B) JavaScript utility for checking deep equality between values of any type, including Objects, Arrays, Sets, Maps, Dates, RegExps, and TypedArrays. It offers a full version and a 'lite' variant with broader legacy browser support but fewer built-in type comparisons.

Use cases

• compare two objects deeply in JavaScript
• check if two arrays are equal
• deep equality check for React dependency arrays
• compare nested JSON structures in tests
• check if two Maps or Sets contain equal values
• tiny deep-equal alternative to lodash.isequal

When to choose

• you need a minimal, dependency-free deep equality check
• bundle size matters and lodash.isequal is too heavy
• you need value equality for Sets, Maps, TypedArrays, or DataViews

When to avoid

• you need IE9 support and Set/Map/TypedArray comparison (use dequal/lite limitations into account)
• you need assertion-style equality with diff output in tests
• you need equality checks for class instances with custom equality semantics
