Sometimes we don't want certain values. Below, Ken doesn't like green or yellow Skittles. Let's discard them.

Try It

const handful = ['green', 'orange', 'red', 'yellow', 'purple', 'green']

const discardGreenAndYellow = discard(['green', 'yellow'])
const goodSkittles = discardGreenAndYellow(handful)
console.log(goodSkittles)
// is ['orange', 'red', 'purple']
const handful = ['green', 'orange', 'red', 'yellow', 'purple', 'green']

const discardGreenAndYellow = discard(['green', 'yellow'])<string[]>
const goodSkittles = discardGreenAndYellow(handful)
console.log(goodSkittles)
// is ['orange', 'red', 'purple']

Try It

const handful = [
  'green',
  'orange',
  'red',
  'yellow',
  'purple',
  'green',
]

const discardGreenAndYellow = discard([
  'green',
  'yellow',
])
const goodSkittles =
  discardGreenAndYellow(handful)
console.log(goodSkittles)
// is ['orange', 'red', 'purple']
const handful = [
  'green',
  'orange',
  'red',
  'yellow',
  'purple',
  'green',
]

const discardGreenAndYellow = discard([
  'green',
  'yellow',
])<string[]>
const goodSkittles =
  discardGreenAndYellow(handful)
console.log(goodSkittles)
// is ['orange', 'red', 'purple']
