Get index of array element

[beescuit]

In javascript, would it be possible to retrieve the index of an element of a ArrayExpr, retrieved via getAnElement, relative to the array?

Try using getElement(int i) instead of getAnElement.

What if I don't know the index? e.g.

const a = [
  {name: "a"},
  {name: "b"},
  {name: "c"}
]

And I want to query the index of the element that has the name "b"?

[smowton]

from int i, Expr bElement, ArrayExpr array
where array.getElement(i) = bElement and
/* check bElement has desired 'name: b' member */
select array, bElement, i

Oh, that feels obvious in hindsight lol. Thank you!
