Sometimes we want to add a constant. Below, we're building a spell for our game that heals for five health. Let's test it on our hero Meg.

Try It

const heal = update({ health: add(5) })

const hero = { health: 2, name: 'meg' }

const healedHero = heal(hero)
console.log(healedHero)
// is {
//   health: 7
//   name: meg
// }
const heal = update({ health: add(5) })

const hero = { health: 2, name: 'meg' }

const healedHero = heal(hero)
console.log(healedHero)
// is {
//   health: 7
//   name: meg
// }

Try It

const heal = update({ health: add(5) })

const hero = { health: 2, name: 'meg' }

const healedHero = heal(hero)
console.log(healedHero)
// is {
//   health: 7
//   name: meg
// }
const heal = update({ health: add(5) })

const hero = { health: 2, name: 'meg' }

const healedHero = heal(hero)
console.log(healedHero)
// is {
//   health: 7
//   name: meg
// }
