(that: Duration): (self: Duration) => boolean
(self: Duration, that: Duration): booleanChecks whether the first Duration is less than the second.
Example (Comparing durations with less than)
import { Duration } from "effect"
const isLess = Duration.isLessThan(Duration.seconds(3), Duration.seconds(5))
console.log(isLess) // truepredicates

Checks whether the first Duration is less than the second.

import orderorder.const isLessThan: <A>(O: Order<A>) => {
(that: A): (self: A) => boolean
(self: A, that: A): boolean
}
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
isLessThan(const Order: order.Order<Duration>Provides an Order instance for comparing Duration values.
Details
NegativeInfinity < any finite value < Infinity.
Example (Sorting durations)
import { Duration } from "effect"
const durations = [
Duration.seconds(3),
Duration.seconds(1),
Duration.seconds(2)
]
const sorted = durations.sort((a, b) => Duration.Order(a, b))
console.log(sorted.map(Duration.toSeconds)) // [1, 2, 3]
Order)
