When writing Typescript functions, what is considered the standard approach? For instance, which of the following three options is preferred:
// Option 1
function myFunction (a: string) {}
// Option 2
function myFunction ({ a }: { a: string }) {}
// Option 3
interface IMyFunction {
a: string
}
function myFunction (input: IMyFunction) {}
Would the choice change if there were three variables instead?
Where can one find reliable reference materials for resolving queries like these?
There are no set rules for handling arguments in functions, much like the debate over using semicolons in JavaScript code. It ultimately comes down to personal preference. Some may prefer using plain arguments when their purpose is clear, while others may opt for objects or interfaces.
For instance, functions like Math.sqrt are straightforward and may be best suited for plain arguments. However, in cases where the meaning of arguments is not immediately obvious, such as in a function like
getUserById(id: number, includeDescription: boolean)When dealing with a large number of arguments, using objects can make it easier to manage and remember their meanings without having to worry about their order. Ultimately, the choice between plain arguments, objects, or interfaces is up to the individual developer's preference.
