Package: effect
Module: Order

Order.isLessThan

Checks whether one value is strictly less than another according to the given order.

When to use

Use when you need a boolean less-than predicate using an Order.

Details

Returns true if the order returns -1, meaning the first value is less than the second. Equal or greater values return false.

Example (Checking less-than comparisons)

import { Order } from "effect"

const isLessThanNumber = Order.isLessThan(Order.Number)

console.log(isLessThanNumber(1, 2)) // true
console.log(isLessThanNumber(2, 1)) // false
console.log(isLessThanNumber(1, 1)) // false

See

• isLessThanOrEqualTo for non-strict less than or equal
• isGreaterThan for strict greater than

Signature

declare const isLessThan: <A>(O: Order<A>) => { (that: A): (self: A) => boolean; (self: A, that: A): boolean; }
