Is it possible for me to use an array as an argument for the rest parameter?

One of the functions in my codebase accepts a rest parameter.

function getByIds(...ids: string){
...
}

I have tested calling getByIds('andrew') and getByIds('andrew','jackson'), which successfully converts the strings into an array of strings.

Now, I am curious if it is possible to call getByIds(['andrew','jackson']) when the parameters are already merged into an array.

In Java, this action would be valid, but I encountered issues with TypeScript and JsFiddle when attempting the same. Any insights on this matter would be appreciated.

Answer №1

Sure thing, you have the option to utilize the spread syntax:

fetchDetails(...['alice', 'smith']);

This will be processed as:

fetchDetails.apply(void 0, ['alice', 'smith']);
