Predicate.isRecord

A refinement that checks if a value is a record (i.e., a plain object). This check returns false for arrays, null, and functions.

Example

import * as assert from "node:assert"
import { isRecord } from "effect/Predicate"

assert.strictEqual(isRecord({}), true)
assert.strictEqual(isRecord({ a: 1 }), true)

assert.strictEqual(isRecord([]), false)
assert.strictEqual(isRecord(new Date()), false)
assert.strictEqual(isRecord(null), false)
assert.strictEqual(isRecord(() => null), false)
