Basically what I'm trying to achieve is to convert an array like this:

 const params = [  
    { name: "name", type: "STRING" },  
    { name: "age", type: "INTEGER" },  
    { name: "admin", type: "BOOLEAN" }  
];  

into a type like this:

{ name: string, age: number, admin: boolean }

I've figured a way to convert individual objects into their proper representation like this:

type ParamType = "STRING" | "INTEGER" | "BOOLEAN";

type GetParamType<T extends ParamType> = 
    T extends "STRING" ? string :  
        T extends "INTEGER" ? number : 
            T extends "BOOLEAN" ? boolean : 
                never;

interface Param {
    name: string;
    type: ParamType
}

type GetTypeFromParam<P extends { type: ParamType }> = 
  P extends { type: ParamType } ? GetParamType<P["type"]> : never;
type GetNameFromParam<P extends { name: string }> = 
  P extends { name: string } ? P["name"] : never;

type FormatParam<P extends Param> = Record<GetNameFromParam<P>, GetTypeFromParam<P>>

type ParamTest = FormatParam<{ name: "test", type: "INTEGER" }> // { test: number }

But I can't figure out how to "concat" an array into a single object. Is there something I can do to achieve this or is it simply impossible to do?

Thanks in advance.

I'm getting an array like this [ {name: 'a', value: 'b'}, {name: 'c', value: 'd'}, {name: 'e', value: 'f'} ]. I need to convert this array to a string, like 'a=b/c=d/e=f' to send to an API. How can I do this? I have tried all sorts of Array map tricks and Object.values or keys stuff to no avail.
