Vanilla JS & ES2015 test cases got broken again in https://trac.webkit.org/changeset/217107

We can't use new Date().getTime() to generate an unique ID.

`vanilla-examples/es2015/src/store.js` has the same line but uses `let` instead of `var` and starts at `1` instead of `0`. Is there a reason for these subtle differences? If so, we may want to add a comment saying so.

That doesn’t seem like the right link.

This bug’s title refers to R220043 but that patch didn’t touch any JavaScript: https://trac.webkit.org/changeset/220043

Did you mean R216718 instead? https://trac.webkit.org/changeset/216718

It looked like all variable declarations in this file was using `var` so I used that to be consistent.

As Mathias asked, is there a reason to use 0 instead of 1 or vice versa?

[Ryosuke Niwa]

Oh oops, clearly, I need to start the value at 1.
