Array question

Question

This is a question from a timed JavaScript Challenge.

What is the output?
var e = [];
e["Yes"] = 7;
console.log(e["Yes"]);
e[null] = 8;
console.log(e[null]);
e[true] = 3;
console.log(e[true]);
e[false] = 2;
console.log(e[false]);

The output is 7832.

Is this an example of non-integer indices? Through Google I found this in Stack Overflow: " JS arrays do not have key indices, those JS objects are considered object literals. so: foo["bar"] = 1; foo.bar === foo["bar"]; //true foo["bar"] === foo[0]; //false This is one of the many subtle quirks about JS that throw people off easily. "

Am I connecting the correct concept with this challenge question?

Thank you in advance!

Answer 1

Yes ~ and sorry for the late response

It creates an object that contains one property. That property has a key name of foo, and that key called foo contains a vaue of "bar"

If you assign the object to a variable, such as baz, you can retrieve the property value by using either array-index notation, or by accessing the appropriate property of that object.
