Using named parameters in JavaScript (based on TypeScript)

True named parameters don’t exist in JavaScript nor in TypeScript but you can use destructuring to simulate named parameters:

interface Names {
    name1: boolean
    name2: boolean
    name3: boolean
    name4: boolean
}

function myFunction({name1, name2, name3, name4}: Names) {
    // name1, etc. are boolean
}

Notice: The type Names is actually optional. The following JavaScript code (without typing) is valid in TS:

function myFunction({name1, name2, name3, name4}) {
    // name1, etc. are of type any
}
