Convert a list to a dict

Question

Im writing a small application i Angular2, and need a simple way to convert a list to a dict.

I have a list:

var list = ["foo", "bar"];

I want to convert the list to a dict like this:

var dict = {foo: "foo", bar: "bar"};

Whats the easiest way to do this using typescript, javascript, jQuery or Angular2?

Looking at that top answer, instead of `obj[v] = 0;`, you'd use `obj[v] = v;` — Cerbrus, May 03 '17 at 11:38
Yes, you are correct. This is a duplicate, thanks for helping out. — Vingtoft, May 03 '17 at 11:39
`["foo", "bar"].reduce((acc, cur) => (acc[cur] = cur, acc), {})` — yurzui, May 03 '17 at 11:40

Try with Array#reduce

var list = ["foo", "bar"];
console.log(list.reduce((a,b)=> (a[b]=b , a), {}))

let list = ["foo", "bar"];

        let dict = {};
        for (let i=0; i< list.length; i++ ) {
                dict[list[i]] = list[i];
        }
        console.log(dict);
