Javascript spread operator

Question

I want to get these properties from an object using es6 directly on the parameters list of the function but I don't know how to do it exactly:

    function methodA(person){
       var driverName = person.name,
       age = person.age,
       company = person.job.company;
       ...
    }

Any tips in that direction?

Answer 1

Take a destructuring assignment.

function methodA(person) {
    var { name: driverName, age, job: { company } } = person;
    console.log(driverName, age, company);
}

methodA({ name: 'Grace', age: 49, job: { company: 'Infinity' } })
