Storing a function in a hash map using TypeScript

Currently, I am faced with a scenario in which I must store functions as values with string keys in lookup tables. These functions serve as handlers with varying names and input parameters but the same return type. When a caller searches for a specific index, it should locate that particular key in the table and retrieve the corresponding function to be invoked accordingly.

As a newcomer to TypeScript, I am unsure of how to approach coding for this situation. Any assistance or guidance would be greatly appreciated.

Answer №1

To achieve this, it is essential to create an interface called IHash.

interface IHash {
    [key: string]: Function
}

const newInterface: IHash = {}

newInterface.methodName = function () { 
    console.log("Executing the method")
}

newInterface.methodName()

Answer №2

const hashTable: IHashTable = {};   

hashTable["key"] = "data"; // assign value

let data = hashTable["key"]; // retrieve value
