Is it possible to define types dynamically in typescript?-CodePudding

I'am getting an array of strings from the server (available image sizes), and I'd like to generate an object out of that array, like this:

[el1,el2...] = { el1:'el1',el2:'el2'...}

So this way when I'am trying to access some value I can see an actual values in the code instead of using indexes. But I don't know what elements my array will consist of, so is there a way of defining types dynamically or maybe another way to achieve the same result?

CodePudding user response：

It sounds like you're asking how to transform an array of strings into an object whose key-value pairs correspond to each value in the array. You can do that with a function like this:

TS Playground link

function asObject (strings: string[]): Record<string, string> {
  const result: Record<string, string> = {};
  for (const str of strings) result[str] = str;
  return result;
}

const array = ['el1', 'el2'];
const obj = asObject(array);
console.log(obj); //=> { el1: "el1", el2: "el2" }
