I have a program in which I wish to prevent anyone from accessing String object or any of its prototypes and I can't seem to find how to do that.
Tried Object.seal, Object.freeze and they both obviously don't work (since they don't prevent you from accessing properties already present, so feeling a little lost on how to do that.
Tried looking it up on internet but after half an hour, all I have got is different way to access properties and 3 ways of adding new stuff and locking but 0 ways to make it be inaccessible
I tried to delete as well but that one was.....
You can use a symbol as a key and store your object in that object. So It will be accessible just in scope you defined the symbol.
function addPrivateKey(a, value) {
let sym1 = Symbol()
a[sym1] = value
console.log(a)
console.log(a[sym1])
}
let a = {};
addPrivateKey(a, 2)
console.log(Object.keys(a))Define a private scope and store your keys there. The values are accessible just with their hints!
class PrivateScope {
glob = {};
#keyToSym = {};
counter = 0;
get(hint) {
return this.glob[this.#keyToSym[hint]]
}
set(value) {
let sym1 = Symbol()
this.glob[sym1] = value
this.#keyToSym[this.counter] = sym1;
return this.counter ++;
}
}
const myPrivateScope = new PrivateScope();
let hint = myPrivateScope.set(2)
console.log(
myPrivateScope.get(hint)
)
console.log(myPrivateScope.glob)
