JavaScript Array to Set

Question

MSDN references JavaScript\'s Set collection abstraction. I\'ve got an array of objects that I\'d like to convert to a set so that I am able to remove (.delete()

Answer 1

If you start out with:

let array = [
    {name: "malcom", dogType: "four-legged"},
    {name: "peabody", dogType: "three-legged"},
    {name: "pablo", dogType: "two-legged"}
];

And you want a set of, say, names, you would do:

let namesSet = new Set(array.map(item => item.name));
