Yeah well that’s regular expressions. ¯\_(ツ)_/¯ Maybe a bit off-topic, but there’s a neat library called Super Expressive that makes working with these a bit easier; the above expression would then look something like this:

const SuperExpressive = require('super-expressive')

const regex = SuperExpressive()
  .wordBoundary
  .capture
    .anyOf
      .string('apple')
      .string('bee')
    .end()
  .end()
  .zeroOrMore.nonWhitespaceChar
  .allowMultipleMatches
  .caseInsensitive
  .toRegex()

const input = 'the beer drinking bee does not l!ke apple-cider'
console.log([...input.matchAll(regex)])
