/**
 * Emits only the index of the first value emitted by the source Observable that
 * meets some condition.
 *
 * <span class="informal">It's like {@link find}, but emits the index of the
 * found value, not the value itself.</span>
 *
 * ![](findIndex.png)
 *
 * `findIndex` searches for the first item in the source Observable that matches
 * the specified condition embodied by the `predicate`, and returns the
 * (zero-based) index of the first occurrence in the source. Unlike
 * {@link first}, the `predicate` is required in `findIndex`, and does not emit
 * an error if a valid value is not found.
 *
 * ## Example
 * Emit the index of first click that happens on a DIV element
 * ```ts
 * import { fromEvent } from 'rxjs';
 * import { findIndex } from 'rxjs/operators';
 *
 * const clicks = fromEvent(document, 'click');
 * const result = clicks.pipe(findIndex(ev => ev.target.tagName === 'DIV'));
 * result.subscribe(x => console.log(x));
 * ```
 *
 * @see {@link filter}
 * @see {@link find}
 * @see {@link first}
 * @see {@link take}
 *
 * @param {function(value: T, index: number, source: Observable<T>): boolean} predicate
 * A function called with each item to test for condition matching.
 * @param {any} [thisArg] An optional argument to determine the value of `this`
 * in the `predicate` function.
 * @return {Observable} An Observable of the index of the first item that
 * matches the condition.
 * @method find
 * @owner Observable
