Static property descriptors

Static property descriptors are standard JavaScript property descriptors. They are applied last thing when a stamp is being composed.
let MyStamp = stampit() // empty stamp creates empty objects
​
MyStamp.name === 'Stamp' // every stamp default name is "Stamp"
​
MyStamp = MyStamp.staticPropertyDescriptors({
  name: { value: 'MyStamp' } // this meta data will be applied just after composition, i.e. immediately
})
​
MyStamp.name === 'MyStamp'
The code above adds some more metadata to the MyStamp stamp. It overwrites function name. (Property descriptors is the only way to change a function name.)
NOTE
The stampit and @stamp/it modules have the "name" feature built in.
const MyStamp = stampit({ name: 'MyStamp' })
MyStamp.name === 'MyStamp'
Other ways to add static property descriptors
Exactly the same stamp can be created in few ways. Here they all are.
const myStampName = {
  name: { value: 'MyStamp }
}
​
const NamedStamp = stampit({
  staticPropertyDescriptors: myStampName
})
​
const NamedStamp = stampit.staticPropertyDescriptors(myStampName)
​
const NamedStamp = stampit().staticPropertyDescriptors(myStampName)
