Typpy: Enhanced Type Checking

JSON →
library 2.4.0 ·javascript
verified Jun 17, 2026

Typpy is a lightweight JavaScript utility that provides a more robust and accurate approach to determining variable types compared to the native `typeof` operator. It addresses common ambiguities of `typeof`, such as `null` evaluating to "object" and distinguishing between different object types like arrays and plain objects. The library allows for type comparison against both string representations (e.g., "array") and constructor functions (e.g., `Array`). Currently at version 2.4.0, its release cadence is moderate, primarily consisting of minor updates for documentation, sponsor links, and small bug fixes like handling null/undefined constructors. It differentiates itself by offering a consolidated API for precise type checks, simplifying conditional logic and reducing potential type-related bugs in applications.
