This method is similar to Array.prototype.find and calls fn on each chunk in the stream to find a chunk with a truthy value for fn. Once an fn call's awaited return value is truthy, the stream is destroyed and the promise is fulfilled with value for which fn returned a truthy value. If all of the fn calls on the chunks return a falsy value, the promise is fulfilled with undefined.

): Promise<undefined | T>;
@param fn
a function to call on each chunk of the stream. Async or not.
@returns
a promise evaluating to the first chunk for which fn evaluated with a truthy value, or undefined if no element was found.
