I attempted
for (const ElementType as element of elements ) {}
or
for (const ElementType of elements as element) {}
However, neither of these options is correct.

No action is required on your part.
interface ExampleElement {
key: integer;
}
const list: TestElement[] = [];
for (const item of list ) {
item // Automatically converted to ExampleElement type

It's interesting that Typescript doesn't support type annotations or assertions on variables within loops like for
/of
. A workaround to achieve similar functionality is by asserting the type of the array instead of the individual elements:
let arr: any = [1, 2, 3, 4];
for (let x of (arr as number[])) {
x // number
}
Although it may seem a bit messy with the additional brackets, it gets the job done.
