Package: effect
Module: Predicate

Predicate.isObject

Checks whether a value is a non-null object value that is not an array.

When to use

Use to narrow unknown input to a non-null, non-array object with a Predicate guard.

Details

This is a structural runtime check using typeof input === "object", so it also accepts object instances such as Date, Map, class instances, and typed arrays. It excludes null and arrays.

Example (Guarding objects)

import { Predicate } from "effect"

console.log(Predicate.isObject({ a: 1 }))
console.log(Predicate.isObject([1, 2]))
