I'm new to typescript and wondering if it's possible to create a function that returns the interface for variable declarations. If so, how can this be accomplished? An example use case (which may not work) could look like this:
let someVar: desiredFunction(name);
const desiredFunction = (name: string) => (name === 'name1') ? Interface1 : Interface2;
While JavaScript is dynamically typed, Typescript can be seen as an extension of it that introduces static typing. Typescript adds types to JavaScript at compile time, meaning that the types are not present during runtime in JavaScript itself. This allows for more robust and error-free code in development.
If you have a generic type with a condition, it can help achieve your desired outcome:
interface Interface1 {};
interface Interface2 {};
const customFunction = <T>(input:T): T extends 'type1' ? Interface1 : Interface2 => {
// implementation here
}
