Convert array of key:value pair objects to string
There are two main approaches for this. The first is pretty straightfoward: do the first bits, then join: data.map(({ name, value }) => `${name}=${value}`).join('/'); You first join the data into an array like this ['a=b', 'c=d', 'e=f'] than just use the String join() function to join those with slashes. The slightly fancier way would be to use .reduce(): data.reduce((str, { name, value }) => `${str}${str ? '/' : ''}${name}=${value}`, '') This one you're just adding each onto the string. This one is a little harder to read, but has the advantage of only one loop through the data instead of two like the other. Better if you're getting lots of data (hundreds or thousands of records). The ternary bit in there (?:) is simply to ensure you don't get a "/" at the start of the string. More on reddit.com

r/typescript on Reddit: [Question] Converting array of objects into a single object
June 5, 2021 -

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.
