import * as R from 'remeda'
import { gt, lt, and } from 'receta/predicate'

// Combine comparisons
const numbers = [1, 5, 10, 15, 20]
R.filter(numbers, and(gt(5), lt(15))) // => [10]

// Multiple conditions
const users = [
  { age: 25, active: true, verified: true },
  { age: 30, active: false, verified: true },
  { age: 35, active: true, verified: false }
]
R.filter(
  users,
  and(
    (u) => u.age >= 25,
    (u) => u.active,
    (u) => u.verified
  )
) // => [{ age: 25, active: true, verified: true }]
