Is there a way to use Typescript.Collections.HashTable in my code?

Question

I see in the code of the Typescript compiler, an implementation of "HashTable" (in the files src/compiler/core/hashTable.ts).

Do you know is there a way I can use it directly in my Typescript project ?

Answer 1

You can implement a very simple hashtable where the key is a string by defining an interface

class Person {
    name: string;
}

interface HashTable<T> {
    [key: string]: T;
}

var persons: HashTable<Person> = {};
persons["bob"] = new Person();
var bob = persons["bob"];

It can only be keyed on a string or a number though.
