greaterThanOrEqualTo

(right: number) => (left: number) => number

Test whether a number is greater than or equal to another

Try It

const gte2 = greaterThanOrEqualTo(2)
gte2(1) // is false
gte2(2) // is true
const gte2 = greaterThanOrEqualTo(2)
gte2(1) // is false
gte2(2) // is true

Try It

const gte2 = greaterThanOrEqualTo(2)
gte2(1) // is false
gte2(2) // is true
const gte2 = greaterThanOrEqualTo(2)
gte2(1) // is false
gte2(2) // is true

Sometimes we want to test for thresholds. Below, we're on a class field trip to Six Flags. Let's see who can ride the roller coaster.

Try It

const heights = {
  sarah: 62,
  matt: 50,
  jason: 58,
  amy: 48,
}

const isTallEnough = greaterThanOrEqualTo(52)
const keepAdmissableRiders = keepWhen(isTallEnough)
const getRiders = compose([keepAdmissableRiders, Object.keys])
const riders = getRiders(heights)
console.log(riders)
// is [
//   sarah,
//   jason,
// ]
type Heights = Record<string, number>
const heights: Heights = {
  sarah: 62,
  matt: 50,
  jason: 58,
  amy: 48,
}

const isTallEnough = greaterThanOrEqualTo(52)
const keepAdmissableRiders = keepWhen(isTallEnough)<Heights>
const getRiders = compose([keepAdmissableRiders, Object.keys])
const riders = getRiders(heights)
console.log(riders)
// is [
//   sarah,
//   jason,
// ]
