Creating an object with the array of a split string

Question

I am trying to create an object using an array that is made using split():

var x = "one two";
var y = x.split(/[^A-Za-z0-9]/)

This gives me an array

[one, two]

Now I want to use that array and create an object using those values, e.g. {one:two}

The following doesn't work:

var z = {};
z.y[0] = y[1];

Can anyone help me out?

The problem is that your code tries to get the property y on the object z (which doesn't exist), then attempts to use that values as an array and set its first element to y[1]. Obviously, z.y is not an array, it is undefined, so it fails.

You need to use array access notation:

z[y[0]] = y[1];

This will use y[0] as a key instead of interpreting it literally.
