There's no secret it's just mystery, straight to the point without hysteria ✨🔮
Basically it is a wrapper of a value, an object that encapsulates this value and implements the map () function.
An example as popular as Rock n Roll or Ronaldinho Gaúcho is the Array in JS, where it is a container (object) that contains a list of values or a dimensional and we have the map function that applies processing to these internal values, so much so that you launch a typeof [🦇, 🐙] will have an object as answer.
Creating your own functor
const secureType = value => ({
value,
map(fn) {
return secureType(fn(this.value))
}
})
//using
const { value } = secureType('who\'s bad?')
.map(text => text.toUpperCase())
.map(text => `${text} 👹`)
console.log(value)

HAHAHA awesome dude
const secureType = value => ({
value,
map(fn) {
console.log(this.value)
return secureType(fn(this.value))
}
})
// using
const { value } = secureType('who\'s bad?')
.map(text => text.toUpperCase())
.map(text =>
${text} 👹).map(text =>
${text} 👹).map(text =>
${text} 👹).map(text =>
${text} 👹)
