What is the best way to specify the data type of a value within a map in TypeScript?

I need assistance defining the value of a key in a map as a key-value pair in TypeScript.

map: {
  key: someStruct
}

Is it possible to declare the type of someStruct and initialize it simultaneously? What is the best approach for accomplishing this?

Answer №1

One way to utilize it is by incorporating it in this manner, and you have the option to allocate it to a variable named x as well

let x = new Map([
        ["key", ["val1"]],
        ["key2", ["val2"]]
    ]);

Answer №2

Although I may not have the complete object, here is a way to achieve it.

Refer to this resource on Interfaces

interface Struct {
   ...
}

interface Map {
   key: Struct
}
const map: Map {
   key: someStruct
}

Alternatively, if you are unable to access the entire object

map: <Map>({
   key: someStruct
})

// or

map: {
   key: someStruct
} as Map
