### 1a. Complete the function definition below. Write a *pure* function the filters a series. Filtering a series should work like filtering an array. Be sure to preserve the type of the series. That is, if the input series has a 'NUMBER' type, then the filtered series should also have a 'NUMBER' type. Example: filterSeries(s1, (x: number) => x > 1) = { type: 'NUMBER', entries: [ { id: 1, data: 2 }, { id: 2, data: 3 } } Example: filterSeries (s1, (x: number) => x === 2) = { type: 'NUMBER', entries: [ { id: 1, data: 2 } } Example: filterSeries (s1, (x: number) => x < 0) = { type: 'NUMBER', entries: [] } export function filterSeries(s: series, f: (arg: T) => boolean): series { throw Error("TODO"):
