Note however that “the number of code points” is not the same thing as “the
actual number of characters” for what a human usually perceives as “character”.
For example:
```js
Object.defineProperty(String.prototype, "codePointCount", {
get() { return [...this].length }
})
"🇨🇦".codePointCount // 2
"n̈".codePointCount // 2
"é".codePointCount // 1
"é".normalize("NFD").codePointCount // 2
```

For what purposes do “most developers” need the number of code points?
