Array destructuring in parameters list, with TypeScript

Question

Using TypeScript, I am trying to figure out how to do array destructuring in the arguments list.

We can use object destructuring like so:

let foo = f         


        

Answer 1

An array of fixed length and types is also called a tuple in TS. We can destructure a tuple argument like:

let bar = function ([desc, opts, fn]: [string, {}, Function]) {


}

bar([
    'yes',
    {},
    function () { }
]);
